In the end it vanished. General coloration: most records of Common Ringed Plover in the States highlight how pale they are above compared to Semipalmated. This is one of the most Common Ringed-like Semipalmated Plovers I've seen; the size and shape of the bill, pronounced and blackish breast band, and apparently dark gape are all quite reminiscent of Common Ringed, and likewise, the eyering is likely within the species’ range of variation. The bird was defending a feeding area close to where I was set up. On these birds, note the: generally delicate structure, with a very narrow rear part of the body; relatively narrow and unbroken breast band of homogeneous width; short, stout bill with a broad base and a typical triangular shape; orangish to reddish patch at the base of the bill; pattern of the upperparts with a broad pale fringe on the feathers of the wing coverts, which contrast with the scapulars and mantle where the feathers have a narrower pale fringe and a dark subterminal line, giving a tricolored appearance (a Cackling Goose-like feather pattern); and. Again, the eyering, red patch at the base of the bill and breast band are quite typical.

It does present other typical features such as a bright orbital ring, red at the base of the bill reaching the bottom of the upper mandible, a uniform breast band roughly concolorous with the back, and a typical pattern to the upperparts. I don't find Semipalmated strikingly dark, so perhaps the difference is only obvious with side-by-side comparisons, or it could be due to plumage variability of Greenland birds (supposedly the ones that reach the States).

It derives from Ancient Greek kharadrios a bird found in ravines and river valleys. Juvenile Semipalmated Plover.

The size of the white tip, particularly in r2 and to a lesser extent in r3, is much smaller in Semipalmated, so that the total amount of white in the tail is less.

However, this feature is usually unnecessary, as pretty much every time you see the bird spread its tail it has also called! Breeding adult Small shorebird with a … Download preview.

One of the very few shorebirds I photographed during this year's fall migration, but at least it was very cooperative! Juvenile Semipalmated Plover. The key identification features for juveniles, such as the bill shape and the presence of white in the gape, are widely known and well described in several papers and field guides - so nothing new here - but I thought it would be interesting to take a detailed look at the variability of these characters for an identification refresher! (CRPL) The juvenile Semipalmated Plovers (SEPL) in comparison were like little wind up toys with cute little rounded heads, like teenage plovers not fully developed physically . It’s time to take a closer look at a few examples of birds in which some of the features are (at least partially) missing: Bird 1. In such surroundings, its seemingly bold pattern actually helps to make the plover inconspicuous, by breaking up its outline against the varied background.
