Nest site selection and efficacy of artificial nests for breeding success of Scarlet Macaws Ara macao macao in lowland Peru

Journal for Nature Conservation, 2014
Psittacidae (parrots) have the most threatened species of any bird family in the world. Most parrots are obligate secondary cavity nesters, and can be limited in their breeding success by the availability and quality of nest hollows. However, nesting opportunities for parrots can be increased by provision of artificial nest boxes.

Airborne Environmental DNA Analysis as a Tool to Monitor Live Bird Trade

Environmental DNA, Volume 8, Issue 2, March/April 2026.
We explore airborne environmental DNA (eDNA) analysis as a novel tool to detect avian species and assess its potential for monitoring bird trade. We collected airborne samples in both enclosed and open market environments, accompanied by visual surveys, and processed them using DNA extraction and metabarcoding to identify avian taxa.

Comparative analysis of microsatellite variability in five macaw species (Psittaciformes, Psittacidae): application for conservation

Genetics and Molecular Biology, 2011
Cross-amplification was tested and variability in microsatellite primers (designed for Neotropical parrots) compared, in five macaw species, viz., three endangered blue macaws (Cyanopsitta spixii [extinct in the wild], Anodorhynchus leari [endangered ...

Migrant Top Management Team and Corporate Innovation: Evidence From China

Accounting &Finance, Volume 66, Issue 1, Page 497-531, March 2026.
ABSTRACT This study explores the association between top management teams (TMT) comprised of migrant managers (migrant TMT) and corporate innovation. Using hand‐collected data for a sample of Chinese A‐share listed firms spanning the period 2008–2020, we find a positive and significant association between a migrant TMT and corporate innovation.

Unruffling the global feather trade: a comparative analysis of CITES and LEMIS records of feathers and bird skins

Wildlife Biology, Volume 2026, Issue 1, January 2026.
During the 18th and 19th centuries, bird feathers (class: Aves) were harvested from wild populations and sold globally in enormous quantities to meet the rising demand of the fashion industry. Although many laws now prevent similar widescale harvest, there is a paucity of studies on the trade that has continued to occur since the 20th century.

Scarlet Macaw, Ara macao, (Psittaciformes: Psittacidae) diet in Central Pacific Costa Rica

Revista de Biología Tropical, 2014
From 1993 to 1997, we observed Scarlet Macaw (Ara macao) feeding behavior in Central Pacific Costa Rica. Feeding data acquired in this study were not collected systematically, but opportunistically whenever macaws were observed feeding. To supplement feeding observations, we conducted interviews with local residents. Scarlet Macaws fed on seeds, fruits,

Response of a Scarlet Macaw Ara macao population to conservation practices in Costa Rica [PDF]

Bird Conservation International, 2005
The Central Pacific Conservation Area contains one of Costa Rica's two viable, but threatened Scarlet Macaw Ara macao populations. For 14 years (1990–2003), we monitored the size of this population. Non-linear models fitted to 1990–1994 observations revealed seasonal and long-term changes in population size.

Conservación de la lapa roja (Ara macao) con manejo in situ en el Pacífico Central de Costa Rica

Ciencias Ambientales, 2019
Desde 1990, la ecología de la lapa roja (Ara macao) en el Pacífico Central de Costa Rica ha sido estudiada. Un análisis preliminar de los conteos entre 1990-1994 demostró una población decreciendo rápidamente, en riesgo de desaparecer en varias décadas ...

Non‐Native Plants Alter Bird‐Plant Frugivory Network Structure in a Human‐Modified Tropical Landscape

Ecology and Evolution, Volume 15, Issue 12, December 2025.
DNA metabarcoding of faecal samples from 21 frugivorous bird species in Gamboa, Panama, was used to assess how non‐native plants influence frugivory network structure. Non‐native species, though comprising only 28% of plants, reduced nestedness, increased connectance and modularity, and caused disproportionately high secondary bird extinctions while ...
