Ruby Crowned Kinglet
The Ruby-crowned Kinglet is a tiny bird that lays a very large clutch of eggs—there can be up to 12 in a single nest. Although the eggs themselves weigh only about a fiftieth of an ounce, an entire clutch can weigh as much as the female herself.
Ruby-crowned Kinglets seem nervous as they flit through the foliage, flicking their wings nearly constantly. Keeping an eye out for this habit can be a useful aid to identifying kinglets.
Metabolic studies on Ruby-crowned Kinglets suggest that these tiny birds use only about 10 calories (technically, kilocalories) per day.
The oldest known Ruby-crowned Kinglet was a female, and at least 8 years, 8 months old, when she was recaptured and rereleased during banding operations in Texas in 2017. She was banded in the same state in 2008.
