Perch selection of three species of kingfishers at the Pantanal of Brazil
Animal Biodiversity and Conservation, 2023 Selecting a suitable perch can offer many benefits for fish–eating birds such as kingfishers. However, factors affecting perch selection in these species remain poorly studied.

Brazilian Journal of BiologyWe investigated the efficiency of different kinds of perches in attracting seed disperser-birds and increasing the seed rain in a degraded area located in the northeast region of São Paulo State. We installed seed traps under natural perches (NPs, living

Influence of Perch-Provision Timing on Anxiety and Fearfulness in Laying Hens
Animals, 2023 Perches can enhance laying hen welfare, but their effectiveness might be age-dependent. We investigated early and late perch access effects on anxiety and fear in pullets through attention bias (AB) and tonic immobility (TI) tests. Pullets (n = 728) were

Influence of rearing environment on development of perching and dustbathing behaviour in laying hens [PDF]
, 2007 Studies have shown that perching and dustbathing behaviour in birds can be affected by how and when the behaviour develops. With the increasing trend away from cages and towards keeping laying hens in larger, more complex housing systems, it is important

Advanced Robotics Research, EarlyView.This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

The Journal of Poultry Science, 2015 The effect of hay bales and perches as environmental enrichment material was investigated on the behavior, heterophil/lymphocyte (H/L) ratio, footpad dermatitis (FPD), and productivity of Japanese broilers in a commercial farm.

Grip and Grasp: Lizard Claw Inspired Robotic Manipulators
Advanced Robotics Research, EarlyView.Our study identifies the most effective lizard claw shape for use as an end effector in a bioinspired robotic manipulator. By examining key geometric features and combining them into comparative indices, the Crotaphytus collaris claw is found to be the best fit.

Coping with compliance during take-off and landing in the diamond dove (Geopelia cuneata). [PDF]
PLoS ONE, 2018 The natural world is filled with substrates of varying properties that challenge locomotor abilities. Birds appear to transition smoothly from aerial to terrestrial environments during take-offs and landings using substrates that are incredibly variable.
