Dunlin or Curlew Sandpiper?

 Birding in early December at Port Charlotte (Florida) Beach Complex on Charlotte Harbor.  Found some "peeps" feeding on the shore.  Are these Dunlins (Calidris alpina), as I suspect?  Or....could they be Curlew Sandpipers (Calidris ferruginea) ?  Dunlins are not uncommon here, but Curlew Sandpipers certainly are.





 We checked out Sibley and Peterson Field Guides....very similar appearing birds.






Size comparison with 7.25" Semipalmated Plover (Charadrius semipalmatus.)








Curlew Sandpiper range map.  Seeing this bird on Florida's Gulf Coast would make it a rare stray!


 Here I don't see a supercillium, but maybe this is a bird just coming into non-breeding plumage?  And the legs are yellow, not black....maybe a Least Sandpiper (Calidris minutilla) but it's bigger than I would expect???

Got to say I am unsure on this ID.....odds on favorite would be Dunlin!  What do you think, my birding friends?

Banded Great Blue Heron

 Spotted this Great Blue Heron (Ardea Herodias) on a recent visit to Stump Pass Beach State Park, and noticed a leg band.  Having seen many Great Blues, but never noticed one to be banded, I sent in a report to the USGS Bird Banding Laboratory....hoping to learn more about this bird.  No luck, but a nice response from biologist Matt Rogosky.



Marker Ref. ID: 82031 encountered 10/19/2016. NCBD (Marker)
I will continue to find out more about this bird's banding...will see if Cornell's Ornithology Lab can help.




Stump Pass Beach State Park is a good spot for shore birds...on a barrier island in Englewood, Florida.


The shifting sands of barrier islands have made the beach walk "wet" during high tide.....but Stump Pass is one of my favorites!

Mailbox moths!

(Thyridopteryx ephemeraeformis) is quite a name for the little critters living on my mailbox!  Common name is Bagworm Moth.





There are over 1000 species in the family Psychidae.  The "bags" here contain the "worm," and are attached by very strong silken threads.



The males become moths and live only a couple of days.  The females lay eggs in their bag and do not emerge as moths.





Usually infesting evergreen, the worms feed on over 50 families of plants and can cause significant damage.  I cannot find any plant damage nearby the mailbox....and postulate that they may indeed be eating junk mail!!!!









These bags are constructed of twigs....they all look similar and are very strong.  The sticks are held together by lots of silk.







Locomotion is achieved by spinning some silk and then dragging the bag along as it moves.  There are silk trails all over the mailbox!
