Canada warbler

It seemed exotic to see a Canada warbler south of the equator.
We are so used to thinking of them as "our" warblers when in fact, they are long distance migrants.

Cardellina canadensis
Not much is known about the mating system of the Canada Warbler, but it appears to be monogamous. The observation of male-female pairs in Panama during fall and spring migration suggests that the pair may stay together year round.
