Sources about cats doesn't look very scientific to me.
Another interesting fact, North Americans cities now have more birds than the same areas had before urbanization because of the abundance of food and lack of predators (other than cats). Also [3] and [4] is the same.
- notsapiensatall 4y agoMaybe, but a lot of those birds belong to a small number of species that won the adaptation lottery, like pigeons. Pigeons are not the sharpest spoons in the drawer, but another name for them is "rock dove". They evolved to live along cliff faces, and to feed simple carbohydrates to their chicks. They can outcompete just about anything in a land full of steep edifices and discarded chips. Corvids, like crows and ravens, don't do quite as well in cities. They are very smart, but they are scavengers who like to nest in trees, and they need protein-rich food like meat for their hatchlings. On the bright side, if you live in a city, you can probably befriend your local crows by tossing them a dollar menu burger every now and then. Seriously, they can recognize faces. Try not to make eye contact until they know you.
- sandworm101 4y agoRe crows/ravens, it depends on the city. In the pacific northwest crows mostly out compete pigeons in urban areas. Ravens have found good homes in semi-rural areas. Hang around Vancouver or Seattle and you will see crows/ravens pushing the eagles around.
- tokai 4y agoNot true about the corvids. They thrive in cities. https://www.mdpi.com/2076-2615/12/14/1820 https://www.mdpi.com/2076-2615/12/14/1820 "The majority (72%, a total of 424 articles) of the studies reported positive effects of urbanization on corvids."
- TillE 4y agoThe astounding claim that cats kill a zillion birds always seem to derive from highly dubious extrapolations from studies of feral colonies.
