Parakeets

there were quite a lot of those loud birds in the little pine grove by the beach in Santa Ponsa. The built complicated-looking nests in the branches, and were easily outnumbering ubiquitous pigeons. there was at least one restaurant named after them (restaurante papagayo), and local-looking people were feeding them - something different from what they fed pigeons, since each feeder attracted either pigeons or parrots, but not both together.

they were obviously not native to balearics, so I made a quick search just now. they are monk parakeets apparently, native to subtropics of Argentina. wikipedia article doesn't list balearics as a home to feral flocks. maybe I should go and correct it.

PS: I just did, but am not sure if the change will stay since I have no source of information that wikipedia would consider appropriate. reference to blog will probably be considered as spam
