UAS-based automatic bird count of a common gull colony [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013 The standard procedure to count birds is a manual one. However a manual bird count is a time consuming and cumbersome process, requiring several people going from nest to nest counting the birds and the clutches.

Referential signaling in a communally breeding bird
Proceedings of the National Academy of Sciences, 2023 Referential signaling, a complex form of communication in which specific signals are associated with external referents, was once thought to be limited to primates. Recent research has documented referential signaling in several other cooperative taxa, predominantly in kin-based societies.

Behaviour of kittiwakes during the breeding season: relationships with nest density and breeding success [PDF]
, 2000 Activity budgets for kittiwakes at the nest site were determined for colonies on Tyneside during the pre-laying period in 1996 and for the Skomer Island colony during the pre-laying period in 1998 and for incubation and chick rearing in 1997 and 1998 ...

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review
Advanced Robotics Research, EarlyView.Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

Molt in Birds Inhabiting a Human-Dominated Habitat
Hayati Journal of Biosciences, 2018 Molt is one of the biological processes in the life of birds that requires high energy. Therefore, it usually occurs when food is abundant. However, molt and breeding overlap have been recorded in the tropics.

Advanced Robotics Research, EarlyView.Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

Ocean control of the breeding regime of the sooty tern in the southwest Indian Ocean [PDF]
, 2007 Food availability, which is often seasonal, is regarded as a key factor in the breeding success of seabirds. In oceanic tropical areas, the resources are mostly patchy and ephemeral at the surface, and the seasonality is less marked than at higher ...

From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures
Advanced Robotics Research, EarlyView.This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...
