The Semipalmated Plover (Charadrius semipalmatus) is an uncommon breeder on the Seward Peninsula. They tend to be found along flat gravel/sand bars on rivers or lake shores. Although during migration they may be found along coastal beaches. They primarily feed on small invertebrates.
These are a smaller plover and look very similar to a Killdeer but has one band rather than two. Their call is very similar sounding to the Golden-Plovers, which sounds like “chu-wee” when in flight. They are almost identical to the Common Ringed-Plover except for the call and a narrower breast band. These can swim short distances as “palmated” means webbed so they have partially webbed feet.
When a predator approaches an adult on a nest, the adult will perform the "broken wing dance" to lure the predator away. This is a similar behavior of that performed by Killdeer as well.

Semipalmated Plovers nest along the coast here on the Northern Seward Peninsula. A couple of adults were seen during the spring (2008) and even some have been viewed during the fall time (2007 & 2008). They are sometimes hunted by young hunters with their pellet guns.
