Avian magnetoreception: elaborate iron mineral containing dendrites in the upper beak seem to be a common feature of birds [PDF]
, 2010 The magnetic field sensors enabling birds to extract orientational information from the Earth’s magnetic field have remained enigmatic. Our previously published results from homing pigeons have made us suggest that the iron containing sensory dendrites ...

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs
The Anatomical Record, EarlyView.Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...

Understanding the spacing of placodes in the eye: A comparative study across age and species
The Anatomical Record, EarlyView.Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.

Analyze the Chosen Production Criteria of Carrier Pigeons
Scientific Papers Animal Science and Biotechnologies, 2023 The aim of this work was to analyze the chosen production criteria of carrier pigeons. We observed the weight of the squabs on the 28th day and their weight before the slaughtering. The slaughtering was carried out before and after the young pigeons left

DYNAMICS OF WAITING IN PIGEONS [PDF]
Journal of the Experimental Analysis of Behavior, 1996 Two experiments used response‐initiated delay schedules to test the idea that when food reinforcement is available at regular intervals, the time an animal waits before its first operant response (waiting time) is proportional to the immediately preceding interfood interval (linear waiting; Wynne & Staddon, 1988).
