Hummingbird seems to be looking for that Hummingbird feeder. Maybe. How big is a hummingbird? How big is a cardinal? How about a turkey vulture? Compare the sizes of the birds and their nests. Ohhh, what about the eggs, what do they look like? How are they they same and different?
The Swallow-tailed Hummingbird (Eupetomena macroura) Its common name and specific epithet (which means "large-tailed") both refer to the long, deeply forked, somewhat swallow-like tail. Found in parts of SA, in semi-open habitat; even gardens and parks within major cities like Rio de Janeiro and São Paulo. the Swallow-tailed Hummingbird is most common among savanna-like vegetation. It is generally a species of lowlands, but occurs locally up to 1,500 m (4,900 ft). Not a true migrant.
