20211102 Common Tern & Caspian Gull RSPB Titchwell

 

20211102 Common tern..??
Short legs and bill, well hooded, but bill not wholly black at advanced juv stage..?
Wet belly feathers obscuring leg length...
Upper tertial has moulted to pale grey.

White secondaries,
short legged again in this shot.

Secondaries darker than ideal and obsured by edge of greater coverts...
Minimal black on primary tips suggest Arctic but Common may have faided by this late date...
Brown-grey tones in upperparts and necky look suggest Common...
Blackish outer tail feathers on both species juvenile stage.

Overall white wing and rump...

20211102 Caspin Gull
Large Gull roost developed on Freshmarsh.
