ARTE 1
Détails de l'observation
My first for this location, and a newly documented location for the eBird map, so quite an exciting encounter and reiterates the importance of the new inlet for not only local breeders but also long-distance migrants. Conditions were good today for this species and I thought I may have a decent chance. About three hours in, and on the higher end of the tide, I discovered two 1st summer individuals resting on flats with some Common Terns. Both birds were sitting within roughly 20 feet of each other and best differentiated by amount of dark flecking on forehead (referred to in photos as ARTE 1 & ARTE 2). Seen both sitting and in flight and in direct comparison to various age Common Terns. Short-legged, round-headed sterna with pale forehead outlined by dark eye and cap extending to nape. Uniform gray primaries on the wing fold with almost a silvery appearance depending on viewing angle. Both birds showing a bit of blotchy gray on underparts, more so on ARTE 1. Leg color was dark with a subtle reddish undertone. Dark bill color and slightly shorter in length than COTE. ARTE 2's bill seemed just slightly longer than ARTE 1 but this may be attributed to viewing distance and angle. Both birds showing kind of a pot-bellied, dumpy look but with attenuated wings and long tail. ARTE 1 spent most of its time preening while ARTE 2 was at rest with its head tucked back, for most of the viewing period. They were not associating with one another but ARTE 2 did eventually pick up and take a short flight over toward ARTE 1 where it landed. Classic underwing pattern noted in flight and well photographed on ARTE 1; neat, thin, dark trailing edge to primary tips. Single gray outer vein on tail also documented in photos and seen well while viewing at close range in the field.
