A Pair of Sharpies


CAPTAIN SAM'S

I banded 11 new birds and had 11 recaptures of 7 different species today.  The excitement came during the 2nd net round when I came up to Net #26 and found 2 Sharp-shinned Hawks!  One was a female that we had banded on 11/15/15 and the other was an unbanded male.  In raptors, the females are larger than males and the size difference was very obvious when they are side by side. Unfortunately, it was impossible for me to get a size comparison photo as I was by myself.  A comparison of the wing and weight may help to highlight the differences.  The female had a wing chord of 199.0 millimeters and weighed 145.8 grams while the male had a wing chord of 158.0 millimeters and weighed 100.0 grams.  The female was 21% larger based on wing and 31% larger based on weight.
