We had an extremely slow day of banding with only 13 new birds and 10 recaptures of 10 different species.
We banded 3 Ruby-crowned Kinglets today - 1 male and 2 females. Ruby-crowned Kinglets can be sexed by the presence or absence of red feathers in the crown with males having red and females without. The red is oftentimes concealed and can only be seen when the bird gets agitated or excited.
