2025. Traslocaci\u00f3n de merlines para proteger al Chorlito silb\u00f3n en los Grandes Lagos<\/strong>.
Translocation of merlins to protect endangered Great Lakes piping plovers <\/h2><\/div>\n\n\n\n


\ud83e\udeb6 \u00bfSab\u00edas que Translocar Merlines (Falco columbarius) podr\u00eda ayudar a proteger al amenazado Chorlito silb\u00f3n?
<\/em><\/strong>
During 2023 and 2024, we evaluated a nonlethal strategy to reduce predation on this critically endangered bird in the Great Lakes:
\u2705 We captured and relocated 33 merlins during the breeding season.
\u2705 We equipped 28 individuals with tracking devices to monitor their movements.
\u2705 We release them between 101 and 404 km from their capture sites.

\ud83d\udcca Key findings:
The 42% did not return to their original territory<\/strong>, temporarily reducing predation pressure
\ud83d\udc49 The females and young individuals<\/strong> were less likely to return
\ud83e\udded The eastward movements<\/strong> were more successful than in other directions
\ud83d\udc4e The distance or date of capture<\/strong> did not significantly influence the return

\u26a0\ufe0f Although it does not replace other measures, translocation can be a useful tool where lethal control is not permitted
\ud83e\udded While translocation can temporarily reduce predation pressure, it is not a solution on its own. We recommend integrating it as a complementary measure within a broader management approach that includes monitoring, deterrence, selective control, nest removal, and alternatives such as temporary housing for problematic individuals.

\ud83d\udce2 This study shows that adaptive management of native predators can help conserve endangered species without eliminating them.

2025. Uso de nidos de Myiopsitta monachus<\/em> por Falco sparverius<\/em> en el centro de Argentina<\/strong>
Use of Monk Parakeet Nests by American Kestrels in Central Argentina <\/h2><\/div>\n\n\n\n

\ud83e\udeb6 Did you know that the American Kestrel (F. sparverius) often uses the communal nests of the Monk (M. monachus)<\/em><\/strong><\/em><\/strong> or breeding?
<\/em><\/strong>
During three breeding seasons in the Cald\u00e9n forest (La Pampa):
\u2705 We recorded 74 nesting attempts of American Kestrels in 49 natural cavities.
\u2705 74.3% occurred in Monk Parakeet nests, 10.8% in excavated cavities, 9.5% in non-excavated cavities, and 5.4% in Brown Cacholote nests (Pseudoseisura lophotes)<\/em>)
\u2705 Monk Parakeet nests were reused in 93.8% of the cases; in 87% of these, the parakeets were still occupying other chambers of the same nest.
\ud83d\udcc8 We found no relationship between cavity reuse and physical characteristics such as orientation, depth, or entrance area.
\ud83c\udf33 Monk Parakeet nests were located both in native trees (mostly cald\u00e9n) and in artificial structures (poles, antennas).

\u26a0\ufe0f These results suggest that the Monk Parakeet acts as an ecosystem engineer, creating key nesting opportunities for the American Kestrel.
\ud83e\udd1d Cohabitation appears to be tolerated by both species and may involve a facultative mutualism.

\ud83d\udce2 This study highlights the importance of interspecific interactions in the nesting ecology of raptors and raises new questions about the benefits and risks associated with the reuse of communal nests.<\/strong>

2025. Un marco para compartir el poder en los equipos de investigaci\u00f3n y promover la justicia en la publicaci\u00f3n cient\u00edfica<\/strong>
A framework for sharing power in research teams and promoting justice in scientific publication<\/h2><\/div>\n\n\n\n

\ud83d\udcda Did you know that the way we organize authorship and editorial processes can reproduce historical injustices?<\/strong>
<\/em>
Between 2023 and 2025, it was proposed:
\u2705 A special collection on the ecology and conservation of cavity-nesting birds in the Neotropics
\u2705 A collective working model based on sociocracy and consent-based decision-making
\u2705 Equitable processes to define authorship, promote the citation of regional literature, and reflect on epistemic justice

\ud83c\udf0e We were 37 authors, 86% affiliated with institutions in Latin America or the Caribbean.
\ud83d\udcca All first authors were affiliated with institutions in the Neotropics
\u26a0\ufe0f Despite the efforts, structural barriers persisted: the hegemony of English, editorial priorities misaligned with the region, and the historical exclusion of local knowledge and voices

\ud83d\udce2 We invite scientific teams to adopt collective, just, and welcoming structures to transform scientific practice from within

The illegal trade of wild birds in a social network: A call for action from Argentina<\/h2><\/div>\n\n\n\n

\ud83e\udd9cDid you know that wild birds are being sold illegally on Facebook?<\/strong><\/em>

Between 2017 and 2023, we detected:
\u2705 Over 154,000 users involved
\u2705 Over 200 active groups in Argentina
\u2705 67 species offered for sale
\ud83d\udea8 Including 3 threatened species (IUCN): Yellow Cardinal, Saffron-cowled Blackbird, and Turquoise-fronted Amazon
\ud83d\udcc9 and 14 species with decreasing populations (IUCN)

\u26a0\ufe0f The illegal trade of birds remains active and visible on social media, despite bans and laws. Over 60% of the groups were public

\ud83d\udce2 We call for urgent and coordinated action among authorities, digital platforms, and civil society to stop this environmental crime

Habitat restoration for the endangered Yellow Cardinal (Gubernatrix cristata<\/em>): a forest treatment without affecting bird diversity at the center of Argentina<\/h2><\/div>\n\n\n\n

\ud83c\udf33 Did you know it's possible to improve the Yellow Cardinal's habitat without harming other bird species?
<\/em><\/strong>
Between 2020 and 2022, we evaluated:
\u2705 A selective mechanical shrub removal treatment to open the understory in Espinal forests (La Pampa)
\u2705 We used 30 sampling points: 20 in control sites and 10 in treated sites
\u2705 We conducted fixed-point survey to assess the bird community.

\ud83d\udcc8 We found that:
\u2705 Yellow Cardinal abundance was significantly higher in treated sites
\ud83d\udcca Species richness, total abundance, and bird diversity did not differ between treated and control sites

\ud83d\udfe1 The Yellow Cardinal is an endangered species, threatened by habitat loss and illegal trafficking
\u26a0\ufe0f Understory opening using machinery proved effective in improving the habitat of this species without affecting the bird community

\ud83d\udce2 We recommend considering this type of forest management as a conservation tool, accompanied by long-term monitoring and institutional coordination.

2024. Ecolog\u00eda y conservaci\u00f3n de las aves que anidan en cavidades en el Neotr\u00f3pico: avances recientes, direcciones futuras y contribuciones a la ornitolog\u00eda<\/strong><\/strong>
Ecology and conservation of cavity-nesting birds in the Neotropics: Recent advances, future directions, and contributions to ornithology<\/h2><\/div>\n\n\n\n

\ud83e\udeb5 Did you know that over 35% of all cavity-nesting bird species live in the Neotropics?
<\/em><\/strong>
In this review, we evaluated:
\ud83d\udcda Advances since 2008 in the study of cavity-nesting birds in the Neotropics
\u2705 Current knowledge on reproductive biology, cavity competition, and types of available cavities
\u2705 The relevance of non-excavated cavities as a primary nesting resource
\u2705 The interaction between human communities, forest management, and cavity availability

\ud83d\udd0d We found that:
\u2705 Most of the cavities used are the result of wood decomposition
\ud83e\udde0 Indigenous and local community knowledge is key to understanding bird\u2013human relationships
\ud83c\udf0e Social, ecological, and cultural factors must be integrated into a socio-ecological systems approach
\u26a0\ufe0f Global lists of cavity-nesting species contain errors for the Neotropics
\ud83d\udce6 We propose reviewing those lists, valuing regional naturalist knowledge, and expanding the concept of \u201cnest networks.\u201d

\ud83d\udce2 We call for a more inclusive and regionally relevant ornithology\u2014one that incorporates natural history, local knowledge, and diverse field studies

2024. Disponibilidad, caracter\u00edsticas y usuarios potenciales de cavidades arb\u00f3reas en el bosque semi\u00e1rido del centro de Argentina<\/strong><\/strong>
Tree cavities and cavity users in two cald\u00e9n forests of Argentina managed as a protected area or for cattle ranching<\/h2><\/div>\n\n\n\n

\ud83c\udf33 Did you know that many birds and mammals depend on tree cavities to survive?
<\/em><\/strong>
Between 2013 and 2014, we studied two types of Calden forest:
\u2705 A protected area (Parque Luro Reserve) and a cattle ranch (Estancia La Tapera)
\u2705 We found 257 cavities in 16 hectares, with an average density of 16.1 cavities\/ha
\u2705 The reserve had 4 times more cavities than the cattle ranch! (19.5 vs. 5.8 cavities\/ha)
\ud83d\udd4a\ufe0f We recorded 44 cavity-using species (35 birds and 9 mammals)
\ud83d\udcc9 6 species have globally declining populations

\u26a0\ufe0f Livestock grazing and the absence of fire reduce the number of available cavities
\ud83d\udea8 Species that nest or take shelter in cavities could be severely affected if the degradation of these forests continues

\ud83d\udce2 We call for the implementation of forest management practices that conserve these critical habitats and promote biodiversity

\ud83d\udc68\u200d\ud83d\udc69\u200d\ud83d\udc66 Did you know that some Yellow Cardinal families can include more than two adults?
<\/em><\/strong>
During the 2020\u20132021 breeding season in La Pampa:
\u2705 We conducted 280 surveys in habitats of the Espinal and Monte regions
\u2705 We recorded 87 individuals: 11 solitary birds, 12 pairs, and 13 family groups
\ud83d\udd0d We also analyzed 1,646 citizen science records from eBird, ArgentiNat, and EcoRegistros

\ud83d\udcc8 We found that:
\u2705 Two family groups (8%) were composed of two adult males, one female, and at least one juvenile
\ud83d\udcca This social structure was not recorded in citizen science platforms
\ud83e\uddec These cases may correspond to cooperative breeding systems or polyandrous groups

\ud83d\udfe1 The Yellow Cardinal is an endangered species, severely threatened by habitat loss and illegal trade
\u26a0\ufe0f This family structure may benefit reproductive success, but genetic and behavioral studies are needed to confirm it

\ud83d\udce2 We propose considering this social variability in future management plans and exploring the possibility of releasing male groups with a female, within a framework of adaptive management and field monitoring<\/strong>

Neotropical ornithology: Reckoning with historical assumptions, removing systemic barriers, and reimagining the future<\/h2><\/div>\n\n\n\n

\ud83c\udf0e Did you know that ornithological science in the Neotropics has historically been shaped from outside the region?<\/em><\/strong>

<\/em><\/strong>In this paper, we analyze:
\ud83d\udcda Advances in Neotropical ornithology despite patterns of exclusion
\u2705 Current strengths: local programs, citizen science, Indigenous knowledge, and regional research networks
\ud83e\udded The systemic barriers that hinder the advancement of ornithology in the region:
\ud83d\udc49 limited funding
\ud83d\udc49 exclusion of leadership roles
\ud83d\udc49 English hegemony and citation bias
\ud83d\udc49 colonial academic structures

\ud83d\udd0d We propose:
\u2705 Adopting collectively governed and regionally led models
\u2705 Prioritizing epistemic justice and the active participation of local communities
\ud83e\udd1d Moving beyond parachute science and recognizing the value of knowledge generated in the Global South

\u26a0\ufe0f Ornithology will not advance unless historical inequalities in knowledge production are transformed

\ud83d\udce2 We invite a deep and anticolonial transformation of the discipline\u2014one that democratizes scientific agendas and acknowledges the diversity of the Neotropics

2022. Biolog\u00eda reproductiva del Coludito Copet\u00f3n (Leptasthenura platensis<\/em>) en cajas nido en el centro de Argentina<\/strong><\/strong>
Reproductive biology of the Tufted Tit-Spinetail (Leptasthenura platensis<\/em>) in nest boxes in central Argentina.<\/h2><\/div>\n\n\n\n

\ud83d\udce6 Did you know that the Tufted Tit-Spinetail can successfully reproduce in artificial nest boxes?
<\/em><\/strong>
During three breeding seasons in the Calden forest (2010\u20132013):
\u2705 We monitored between 82 and 101 boxes per season, every 1 to 3 days.
\u2705 We analyzed variables such as occupancy, nesting success, clutch size, and sex ratio

\ud83d\udcc8 Results:
\u2705 10.6% of the boxes were occupied by Tufted Tit-Spinetail
\u2705 The reproductive cycle lasted 33 days, with an incubation period of 14.2 days and a nestling period of 13.6 days.
\ud83d\udcca Average clutch size: 3.41 eggs | Fledglings per successful nest: 2.78
\ud83d\udcc8 Daily nest survival rate: 98.3% | Nesting success: 56.9%
\u2696\ufe0f The sex ratio was balanced (15 males, 15 females)
\u26a0\ufe0f Pine and PVC boxes were used more frequently than Calden boxes, indicating that box type influences occupancy

\ud83d\udce2 This work expands our knowledge of the natural history of the Tufted Tit-Spinetail and highlights the value of nest boxes as a tool for studying and conserving cavity-using species<\/strong>

Dietary ecology of two migrant flycatchers in habitats with and without cattle during the breeding season in central Argentina<\/h2><\/div>\n\n\n\n

\ud83e\udeb0 Did you know that livestock grazing can influence the diet and reproductive success of insectivorous migratory birds?<\/em><\/strong>

<\/em><\/strong>Between 2015 and 2019, we studied:
\u2705 Two species of flycatchers: the Vermilion Flycatcher (Pyrocephalus rubinus<\/em>) and the Fork-Tailed Fly catcher (Tyrannus savana<\/em>)
\u2705 Grazed and ungrazed habitats in the Espinal region (La Pampa)
\u2705 Diet analysis using fecal samples and prey abundance assessment through sweep transects

\ud83d\udcc8 We found that:
\u2705 Both species primarily consumed hymenopterans and coleopterans; the Fork-tailed Flycatcher also consumed orthopterans
\u2705 Vermilion Flycatchers had lower reproductive success in sites with higher numbers of hemipterans
\u2705 Fork-tailed Flycatchers showed higher reproductive success in areas with greater coleopteran abundance
\u26a0\ufe0f Prey abundance was higher in the reserve without livestock
\ud83c\udf7d\ufe0f Both species selected certain prey groups over their environmental availability

\ud83d\udce2 Livestock grazing alters food availability and influences the reproduction of these birds. It is essential to consider these effects in conservation planning

<\/em><\/strong>
\ud83d\udccd On December 23, 2020, we recorded:
\u2705 A Swallow-tailed Kite flying over grasslands near Pehuen-C\u00f3, Buenos Aires Province (38\u00b059\u201900.4\u201dS, 61\u00b033\u201906.4\u201dW)
\u2705 It was attacked by a Chimango CaracaraMilvago chimango<\/em>) while flying over dunes with scattered trees
\ud83d\udcf8 We obtained photographic evidence of the event

\ud83d\udcc8 This record represents:
\u2705 The southernmost known record for the species worldwide
\u2705 An extension of its range at least 130 km south of the previous known record (Necochea)
\u26a0\ufe0f This event provides new data on interspecific interactions of the Swallow-tailed Kite and its occasional presence in southern Argentina.

<\/em><\/strong>During three breeding seasons (2015\u20132018) in the Pampean Espinal
\u2705 We captured and banded 96 individuals of Tyrannus s. savana<\/em> (43 males, 42 females, 11 unsexed)
\u2705 We measured biometrics, body condition, reproductive status, and molt
\u2705 Sex was determined by plumage or through molecular methods in the laboratory

\ud83d\udcc8 Results:
\u2705 Males were larger than females in weight, wing length, and tail length
\u2705 Most adults showed low fat accumulation, intermediate muscle development, and minimal plumage wear.
\u2705 The incubation patch was highly developed in females, while the cloacal protuberance was small in males
\ud83e\udeba Flight feather molt was generally absent during the breeding season
\u26a0\ufe0f We detected interannual variation in fat accumulation and feather wear, possibly linked to environmental conditions
\ud83d\udcc9 As the breeding season progressed, adult body weight decreased and development of the incubation patch increased

\u2705 We captured and banded 93 Vermilion Flycatchers at three sites: one nature reserve and two cattle ranches
\u2705 We measured biometrics, body fat, and reproductive traits
\u2705 We calculated body condition indices and analyzed their relationship with sex, age, date, and habitat type

\ud83d\udcc8 Results:
\u2705 Females weighed more and accumulated more fat than males
\u2705 No differences were found by age, date, or year.
\u26a0\ufe0f The only factor explaining body condition was the site: it was significantly lower at one of the cattle ranches

\ud83d\udce2 This study suggests that livestock grazing may affect the physiological condition of the Vermilion Flycatcher. Protected areas appear to offer better conditions for its reproduction

2021. No es una tendencia global: la latitud no influye en la orientaci\u00f3n cardinal de las cavidades excavadas por aves en el hemisferio sur<\/strong><\/strong>
Latitude does not influence cavity entrance orientation of South American avian excavators<\/h2><\/div>\n\n\n\n

\ud83e\udded Did you know that, unlike in the Northern Hemisphere, excavating birds in the south do not orient their cavities based on latitude?<\/em><\/strong>

<\/em><\/strong>We analyzed:
\u2705 1,501 cavities excavated by 25 bird species (mainly woodpeckers)
\u2705 Data collected across 12 ecoregions from 15\u00b0S to 55\u00b0S
\u2705 We applied circular Bayesian mixed models and multi-model analysis.

\ud83d\udcc8 Results:
\u2705 No relationship was found between latitude and cavity orientation
\ud83d\udcca Cavity orientations were diverse: 5 ecoregions showed bimodal patterns, 4 unimodal, and 3 uniform
\u2705 In several cases, the models showed high uncertainty regarding the predominant pattern

\u26a0\ufe0f These results contrast with those from the Northern Hemisphere, where equator-facing patterns are commonly observed
\ud83c\udf0e Local factors (wind, vegetation cover, topography) and oceanic influence may explain the variability observed in South America

\ud83d\udce2 We propose reanalyzing Northern Hemisphere patterns using multi-model approaches and considering local environmental variables when studying cavity orientation at a global scale

2020. S\u00edntesis de la historia ornitol\u00f3gica de la provincia de La Pampa, Argentina<\/strong><\/strong><\/strong>
A synthesis of the ornithological history of La Pampa province, Argentina<\/h2><\/div>\n\n\n\n

\ud83d\udcdc Did you know that the first records of birds in La Pampa (excluding rock art) date back to the early 19th century?<\/em><\/strong>

<\/em><\/strong>In this systematic review, we analyzed:
\u2705 225 references published between 1806 and 2020
\u2705 Classified by publication type and topic (ecology, conservation, distribution, methodologies, etc.)
\u2705 Distributed across four historical periods:
1\ufe0f\u20e3 Early contributions (1808\u20131879)
2\ufe0f\u20e3 Traveling naturalists and old-school scientists (1880\u20131959)
3\ufe0f\u20e3 Beginnings of modern science (1960\u20131999)
4\ufe0f\u20e3 New millennium (2000\u20132020)

\ud83d\udcc8 Main findings:
\u2705 Since 2000, there has been an exponential increase in ornithological scientific output in La Pampa
\u2705 Institutions, methods, and forms of outreach diversified
\u2705 The category \u201cnatural history and ecology\u201d was the most frequent (44% of the publications)
\ud83e\udde0 Participation in citizen science and interinstitutional collaboration also increased

\u26a0\ufe0f The Pampas region has undergone significant environmental changes affecting bird populations
\ud83d\udce6 The province has a low percentage of protected areas and faces conservation challenges

\ud83d\udce2 This historical synthesis helps us understand how bird studies evolved in La Pampa and outlines a clear path for future research, management, and conservation

2020. Selecci\u00f3n del lugar de nidificaci\u00f3n y \u00e9xito reproductor de dos aves migratorias neotropicales australes en un bosque semi\u00e1rido: Una comparaci\u00f3n de lugares con y sin ganado<\/strong><\/strong><\/strong>
Nest-site selection and breeding success of two neotropical austral migrant birds in a semiarid forest: A comparison of sites with and without livestock<\/h2><\/div>\n\n\n\n

\ud83e\udeb6 Did you know that livestock grazing can influence the reproductive success of some migratory birds, but not necessarily their nest site selection?<\/em><\/strong>

During two breeding seasons (2015\u20132017) in the Pampean Espinal (La Pampa):
\u2705 We studied two migratory species: the Vermilion Flycatcher (Pyrocephalus rubinus<\/em>) and the Fork-Tailed Fly catcher (Tyrannus savana<\/em>)
\u2705 We compared sites with and without livestock grazing (a reserve and two ranches)
\u2705 We evaluated nest site selection at micro- and macro-scales, and reproductive success

\ud83d\udcc8 Results:
\u2705 The Vermilion Flycatcher selected sites with greater tree cover, while the Fork-tailed Flycatcher chose taller plants with thinner trunks
\u2705 Reproductive success was low: 12.7% in Vermilion Flycatchers and 28.7% in Fork-tailed Flycatchers.
\u26a0\ufe0f Vermilion Flycatcher reproductive success was lower in grazed sites, while Fork-tailed Flycatcher success did not vary
\ud83c\udf2c\ufe0f For Fork-tailed Flycatchers, nests oriented east had higher survival, possibly due to protection from strong wind

\ud83d\udce2 Although both species use diverse habitats, livestock grazing may reduce Vermilion Flycatcher success, and the structural heterogeneity of nature reserves seems to favor its reproduction<\/strong>

2018. Primera registro del Loro Barranquero (Cyanoliseus patagonus<\/em>) anidando en cavidades arb\u00f3reas<\/strong><\/strong><\/strong>
First report of Burrowing Parrot (Cyanoliseus patagonus<\/em>) nesting in tree cavities<\/h2><\/div>\n\n\n\n

\ud83c\udf33 Did you know that the Burrowing Parrot, which usually nests in cliffs, has been observed nesting in trees?<\/em><\/strong>

<\/em><\/strong>During the 2016\u20132017 breedinf season at Parque Luro (La Pampa):
\u2705 We documented two nesting attempts in cavities of live Calden trees.
\u2705 The cavities were located between 3.1 and 5.3 meters high
\u2705 At one of the nests, we observed three successfully fledged young

\ud83d\udcc8 This is the first documented record of the species using tree cavities as a nesting substrate
\ud83d\udcca The scarcity of cliffs in the area and the presence of a colony of Blue-crowned Parakeet (Thectocercus acuticaudatu<\/em>s) may have favored this behavior
\u26a0\ufe0f The species showed flexibility in nest site selection, which could have implications for its reproductive ecology in cliff-less environments

\ud83d\udce2 This finding suggests that the Burrowing Parakeet could adapt to new breeding substrates and highlights the importance of Calden forests as alternative habitat.

2018. Registros de Halc\u00f3n Negro Grande en zonas urbanas del noroeste de Argentina<\/strong><\/strong><\/strong>
Records of Orange-breasted Falcons in Urban and Suburban Areas of Northwestern Argentina<\/h2><\/div>\n\n\n\n

\ud83c\udfd9\ufe0f Did you know that a rare raptor for Argentina was observed in urban areas of the northern part of the country?<\/em><\/strong>

<\/em><\/strong>In 2016, we recorded:
\u2705 Observaciones regulares de Halc\u00f3n Negro Grande (Falco deiroleucus<\/em>) en las localidades de Palma Sola (Jujuy) y San Jos\u00e9 de Met\u00e1n (Salta)
\u2705 The records were made during winter, in urban and peri-urban environments surrounded by crops and remnants of piedmont forest
\u2705 We observed the birds perched, in flight, and feeding on prey such as pigeons and thrushes

\ud83d\udcc8 This pattern suggests:
\u2705 Seasonal altitudinal movements from montane forests to lowland areas during winter
\u2705 Possible use of urban areas as foraging sites, taking advantage of high prey availability
\u26a0\ufe0f The Orange-breasted Falcon is a rare species typically associated with mature Neotropical forests
\ud83c\udf06 These observations suggest greater ecological flexibility than previously thought

\ud83d\udce2 It is necessary to investigate the factors driving these movements and assess the potential risks and opportunities that urban areas present for the species

Reproductive parameters of the Turquoise-fronted Parrot (Amazona aestiva<\/em>) in the dry Chaco forest<\/h2><\/div>\n\n\n\n

\ud83e\udd9c Did you know that the Blue-fronted Amazon (Amazona aestiva) can lay up to 6 eggs and successfully breed in extreme environments of the Chaco?
<\/em><\/strong>
During five seasons (2002\u20132006) at the Loro Hablador Provincial Park:
\u2705 We monitored 98 active nests in a protected dry forest in the Chaco
\u2705 We estimated clutch size, hatching success, fledging success, and brood reduction
\u2705 We measured eggs, survival rates, and causes of loss

\ud83d\udcc8 Results:
\u2705 Average clutch size: 3.7 eggs | Hatching success: 73% | Fledging success: 88%
\u2705 Brood reduction was the main cause of chick loss, associated with large and late clutches
\ud83d\udcca On average, each pair produced 0.95 fledglings per season
\u26a0\ufe0f Clutches were highly synchronized, and no replacement attempts were recorded
\ud83c\udf21\ufe0f High temperatures could affect incubation and embryo development
\ud83d\uded1 Legal extraction of chicks is conducted at advanced stages, targeting viable individuals, which poses risks to sustainability

\ud83d\udce2 This study provides key evidence to review legal harvest models and improve the management of this emblematic species

Contributions to the breeding biology of the Saffron Finch (Sicalis flaveola<\/em>) in nest
boxes in a semi-arid forest in central Argentina<\/h2><\/div>\n\n\n\n

\ud83d\udfe1 Did you know that the Saffron Finch (Sicalis flaveola) can successfully breed in nest boxes placed in dry forests of the Espinal?<\/em><\/strong>

During two breeding seasons (2011\u20132013) in a Calden forest (La Pampa):
\u2705 We checked 101 nest boxes in 2011\/12 and 99 in 2012\/13, recording 17 active Saffron Finch nests
\u2705 We monitored reproductive parameters: clutch size, success, incubation period, and nestling duration
\u2705 We determined the sex of the nestlings using molecular techniques

\ud83d\udcc8 Results:
\u2705 Average clutch size: 4.10 eggs | Incubation: 11.1 days | Nestling period: 14 days
\ud83d\udcca Overall reproductive success: 58.6% | Success per nest: 3.66 nestlings (range: 2\u20135)
\u2696\ufe0f Balanced sex ratio: 13 males and 14 females
\u26a0\ufe0f We detected six nestlings with dermatitis caused by mites (Ornithonyssus bursa<\/em>)
\ud83d\udc2d There was nest predation by rodents (Graomys griseoflavus<\/em>) and marsupials (Thylamys pallidior<\/em>)
\ud83e\udd87 We recorded the simultaneous occupation of a nest box by a Southern Yellow Bat (Lasiurus ega<\/em>)

\ud83d\udce2 Despite the low occupancy rate, this study provides valuable data on the reproduction of the Saffron Finch in semi-arid environments and highlights the usefulness of nest boxes as an ecological tool<\/strong>

Records of five-egg clutches and five nestlings for the Tufted Tit-Spinetail (Leptasthenura platensis<\/em>) in nest boxes in La Pampa Province, Argentina<\/h2><\/div>\n\n\n\n

\ud83d\udc23 Did you know that the Tufted Tit-Spinetail can successfully raise complete broods of five nestlings in nest boxes?<\/em><\/strong>

<\/em><\/strong>Between 2005 and 2013, we monitored:
\u2705 100 nest boxes installed in a Pampean Calden forest
\u2705 58 active nests of Tufted Tit-Spinetail
\u2705 We identified four five-egg clutches, one of which was completely successful: all five nestlings fledged

\ud83d\udcc8 Results:
\u2705 Average occupancy rate: 9.5%
\u2705 Only 10.8% of complete clutches had five eggs
\u2705 First documented case of complete reproductive success with five nestlings in a single brood for the species
\u26a0\ufe0f One documented predation case was caused by a White-bellied fat-tailed mouse opossumThylamys pallidior<\/em>)


\ud83d\udce2 These data expand knowledge on the reproductive history of the Tufted Tit-Spinetail and demonstrate the potential of nest boxes to record rare reproductive events in semi-arid environments<\/strong>.
