Re: Oso Flaco Lake Black Tern

Just wanted to add that photos taken today show that this bird is in juvenile plumage. Some photos show the brownish back, nape and forehead expected on a juvenile.


Those submitting eBird lists may want to indicate the age on the checklist and label their photos as “juvenile”.

The Oso Flaco Black Tern continued till after 5pm this afternoon. It was visible feeding over the lake, looking south from the wide spot a little before the the coastal end of the boardwalk that goes across the lake. It only came close once. The rest of the time it was at least half way across the lake, flying with swallows.
