A characteristic feature of puddles is that they gather birds. There they go to bathe: a way to keep their feathers fit. These are neutral areas, where the degree of conflict seems null. No bothering, no interfering, each one in his own business. The priority is a valueless treasure for birds: their feathers. In the same puddle a Bay-winged Cowbird and a Sooty-fronted Spinetail in a dip. Standing or squatting they splash water all over themselves. Once feathers are wet they move away to dry them. The Black-and-rufous Warbling-Finch is indecisive and the Ultramarine Grosbeak approached only to take a sip. Not far away was a male Ultramarine Grosbeak which flew by and was joined by the bird in puddle.
