A ruby-crowned kinglet (Regulus calendula) searches for insects while briefly perched on the fork of an elm tree in Snohomish County, Washington. Ruby-crowned kinglets are very small birds with a length of about 4 inches (10 centimeters) and a wingspan of about 6 inches (16 centimeters). They typically weigh just 5 grams (0.2 oz), which is about the weight of a U.S. quarter dollar coin.
