Re: [cobirds] Re: Lake Henry sandpiper

And just to stir the pot a bit, here photos taken by Mark Peterson of the same bird the previous day (when it was found), under very different lighting conditions (bright and sunny, vs my photo under overcast).

 Again, thank you Mark!

Compare the Lake Henry bird to these photos of
Rock Sandpiper: https://macaulaylibrary.org/asset/312705731

and Purple Sandpiper: https://macaulaylibrary.org/asset/433376671

In my opinion, its wing stripe looks better for Purple. But I have basically no experience with either species. Like most of us, I'm waiting for the experts to look at the photos.

As for bill color, I defer to someone familiar with young Rock Sandpipers to determine if the extent and coloration is in the norm for that species or if this would indicate a Purple Sandpiper instead.

COBIRDERS,

 

I've attached a number of photos showing different views/angles of the PURPLE/ROCK SANDPIPER.  The very pale underwings and thick, white upperwing seem consistent with Rock Sandpiper (however I do not know about immature plumages of Purple Sandpiper).  The bill and leg color and the overall face pattern look better for Purple Sandpiper.

 

Purple Sandpiper is more likely distribution-wise, but "birds have wings".

 

Perhaps someone can forward the below link to Paul Lehmann since he has extensive experience with Rock Sandpipers in juv. and imm. Plumages.

 

Below is the link…you all can view and consult various references.
