American tree swallow watching the sunset (Sumpfschwalbe | Hirondelle bicolore)

This is the same bird that I posted yesterday, just from a “slightly” different angle. In this picture the glossy blue upperparts are well-visible as well as the difference to the black wings and tail.

 

The genus genus name Tachycineta translates to “moving quickly” from Ancient Greek “kinein” - to move - and “takhys” meaning rapid or fast. Bicolor refers to the swallow being two-colored although it could maybe be either considered monocolored for the blue upperparts or tricolored if you want to count black and white as colors too. ;)
