觀察細節
A juvenile intermediate (in color) Long-tailed Jaeger was present in the southeast corner of Pond 2 at Hornsby Bend on the morning and early afternoon of 8-31-17. The bird was swimming and actively feeding during the 85-minute period during which I observed it. The bird did not fly. The bird had a gray head and a pale bill with a dark tip. The throat appeared gray and lightly streaked and the breast appeared heavily streaked. The vent and under-tail coverts appeared heavily barred. The bird's scapulars, lesser, median and greater coverts,and tertial feathers were dark with pale tips. The bird's primary feathers appeared dark without noticeable pale tips.
