This was a small hawk, but I'm basing the ID on the rounded tail feathers.
Shell approximately 4" lengthwise down center and 3 1/2" at widest point. Height of shell about 2 1/2"
Found shell as shown upside down near cedar fence post on south side of property.
Estos pajaritos son bien bravos! Se me han echado encima al tratar de fotografiarlos. Y en una ocasión me tocó ver una de las cosas más impresionantes que he visto: entre tres persiguieron a una ardilla que se acercó de más al nido. Fue impresionante!
Growing on Ulmus alata.
