Over 2,000 pigeons were shot at UK railway stations and depots in 16 months, revealed by BBC data obtained via the Freedom of Information Act. While operators cite safety and health hazards from droppings, animal welfare advocates criticize the "inhumane" method, proposing alternatives.
Roost, a 'slow-cial' app, uses virtual birds to deliver messages, contrasting with instant communication. It gained viral popularity, growing from 10,000 to 300,000 users, praised for its wholesome and intentional communication.
Des biologistes de l'Institut Max Planck ont découvert que les pigeons voyageurs s'orientent grâce à une boussole magnétique dans leur foie, formée par des macrophages réagissant au champ magnétique, en complément de la navigation solaire.
A new study suggests pigeons use specialized immune cells in their livers and spleens, which accumulate iron, to sense Earth's magnetic field for navigation. Removing these cells impaired their ability to find their way home, especially in cloudy conditions.
Une équipe allemande propose un quatrième mécanisme expliquant l'orientation des pigeons voyageurs, impliquant le foie et les particules d'ions ferriques, s'ajoutant aux théories précédentes sur le bec, l'œil et l'oreille.
