The pectoralis muscle orientation as an indicator of the modes of wing-propelled locomotion in birds. [PDF]

J Anat
The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Does Participatory Bird Monitoring Provide Accurate Data for Ecological Research? An Experience in Rural Southwestern Mexico. [PDF]

Ecol Evol
Trained local people are capable to conduct bird monitoring and generates useful data for testing ecological hypotheses related to anthropogenic impact. Scientific endeavors based on community projects should develop training strategies aimed at enhancing monitors' skills in both bird identification and abundance recording.

The link between colorfulness and extinction risk across the world's passerine birds. [PDF]

Conserv Biol
Abstract Many of the functional traits that mediate extinction risk across the range of biodiversity relate indirectly to a species’ ability to persist in a changing world, yet certain traits such as coloration directly affect human interactions with wildlife.

Changing Rainfall Drives Locally Asynchronous Reproduction of Tropical Birds via Modular Trophic Pathways. [PDF]

Glob Chang Biol
In low‐latitude mountains, we found insectivorous bird communities switched from breeding before to after the dry season at a threshold in dry‐season insects. Localized breeding season reversal of insectivores across wet‐to‐dry gradients magnified short‐term effects of drought and contrasted with the seasonal stability of nectar‐fruit consumers.

Sapsucker Wells as a Keystone Nutritional Resource: Evaluating Methods for Detection of Secondary Sap Consumers. [PDF]

Ecol Evol
We used direct observations, camera traps, and environmental DNA (eDNA) to identify secondary consumers of sap from wells created by red‐naped (S. nuchalis) and Williamson's (S. thyroideus) sapsuckers among three groups of shrubs and trees in south‐central Colorado, USA.

Ocorrência e evolução da vocalização em alta frequência em beija-flores (Aves: Trochilidae) [PDF]

, 2023
The growing number of studies in bioacoustics has brought to light previously unknown behaviors for several animal groups, such as the ability of hummingbirds (Aves: Trochilidae) to vocalize at high frequencies (i.e., peak frequency >10kHz).
