Cats have around 500 taste buds on their tongue, dogs 2,000, humans and pigs 15,000 and birds only a few dozen to a few hundred.
Sometimes this is helpful because birds can eat distasteful fruits and nuts that rodents are repelled by. It is thought that some plants have evolved a bad taste in order to be dispersed by birds rather than mammals. While rodents tend to chew seeds and fruit, birds often swallow them whole, maikng them much more likely to germinate later.

This photo above of me and a mockingbird was taken in the Galapagos Islands a few years ago. The mockingbird is on my shoulder not because it thinks I'm wonderful :-( but because I am holding a water bottle. While there is plenty of salt water on/around the island, there is very little fresh water. The birds seem to have learned that it is "work" for the body to desalinate the salt/sea water and therefore, they try and get fresh water from the tourists. If you accidentally drop your water bottle on the ground there, you will have a flock of birds around it in seconds, hoping to get a little drop of fresh water! This guy on my shoulder was hoping I would open my bottle and pour some out for him.
Do you notice any favorite tastes in the birds around you?
