He looked very dead when he was brought inside the kitchen, but I protected his body from the cats and put a tupperware on top. He came back to life, the bird, and started trashing in the tupperware: and I took him outside where he flew away....Om shanti om! Long life to you little unidentified bird! May you flourish!

UPDATE

Yellow-rumped warbler was a female bird I saved today. (Paruline a croupion jaune)

This is the specie: HERE.

The photo is from the above site.

For the song of the male warbler yellow rumped go HERE, from Quebec.
