Domestic chickens can be observed to have different states of alertness. Hens exhibit fear by increasing the time spent standing alert and increased preening. Before empathy in chickens was reported, other investigations demonstrated that hens avoid environments associated with higher preening rates and standing. [4]
OMAHA, Neb. (AP) — Bird flu is forcing farmers to slaughter millions of chickens a month, pushing U.S. egg prices to more than double their cost in the summer of 2023. And it appears there may ...
Bird flu is primarily spread by wild birds such as ducks and geese as they migrate. While it is fatal to a variety of animals, those species can generally carry it without getting sick, which offers the virus a chance to mutate and thrive. The virus can be spread through droppings or any interaction between farm-raised poultry and wild birds.
Dogs presented with images of either human or dog faces with different emotional states (happy/playful or angry/aggressive) paired with a single vocalization (voices or barks) from the same individual with either a positive or negative emotional state or brown noise. Dogs look longer at the face whose expression is congruent to the emotional ...

How do birds get their colors? Understanding bird coloration combines biology and physics. There are two primary ways that birds get their color: pigmentation and the physical structure of the ...
Upon hatch, birds do not have a library of genetic information for B cells to use for antibody production. Instead, J cells mature in the bursa during the first six weeks and then go on to seed other organs of the immune system. As a result, birds are highly susceptible to pathogens in the first few weeks after hatching.
