A Plover Crash Course... of Sorts!

Sept 27/28/29 Boundary Bay 96-104 St Delta BC. 
If I ever thought flycatchers were difficult to identify then the American golden plover and its close cousin the Pacific golden plover come in a very close second.
The species can be next to impossible for the novice to identify and even experienced birders sometimes have to take a second look. 
Even scoping in the company of experienced birders, identification can still be a challenge. Tell tale signs like the presence of the long wingtips on the American is diagnostic, while on the Pacific, tail feathers don't protrude beyond the tail. Simple Eh, Hmmm! 
But what if the bird is facing you (most times they are) and to that add a mixture of juvenile adult non-breeding and adult breeding birds in the same flock then the challenge of identification become more difficult. 
Just to confuse matters, telling Pacific and Americans apart (below) is again confused by some juvenile black-bellied plovers. Note the stout bill and the golden wash of the bird below, it tricked me for a moment into thinking it was the scarcer American golden plover.

Even with a scope, identification can be difficult. For the purpose of this blog I spent three evenings photographing all three species, but especially the rarer American and Pacific.
On each occasion I would check to see if there were any other birders around before I walked out to get a closer view. There weren't. The tide was far out so I walked along the beach until I spotted six plovers mixed in with a small flock of western sandpipers and dunlins. As I drew closer I could see that the plovers were more dainty and slimmer billed than the commoner black-bellied plovers. Besides they acted differently allowing me to creep up on them, something black-bellies won't normally allow. Americans and Pacific that mix-in with black-bellied are almost impossible to approach.

Back home I had  four birds books laid out on the table trying to work out which of the two species was which. I even posted my photos and only had two responses, both who erred on the cautious side. So, if you see I have mis-identified any of the pictures below please feel free to drop me an e-mail.

Often the American and Pacific goldens feed on the edge of the larger black-bellied plover flock.

This bird is easier to identify than juvenile and non-breeding adults but if possible try to get a side angle as in the picture below so as to share the photos with the experts who help identify between the two species.

Plovers are not the only birds on the beach. American Pipits have been passing through most of September. Sometime flocks of fifty gather in the fields while along the dike pairs can be seen feeding on insects, sometimes they feed alongside pectoral sandpipers.

American Pipits are often found in pairs.

Meanwhile.....

Small flock of pectorals continue to feed right up to the edge of the dyke even when the water is way out.

This sandpiper came so close I could almost touch it.




Black-bellied plover are mostly gray overall and the commonest plover in Boundary Bay.

Parting Shot

As the sun sets so does the quality of light. Often referred to as" sweet light" this light adds a golden wash to everything including this flock of black-bellied plovers which a few hours earlier (above) were gray in colour. Can you see identify the odd bird out?

  1. John, thanks for the crash course! I'm afraid I'll probably still go on in a haze, and have to refer to the old Sibley! Glad I have a camera and can now pretty well do my Identifying in the comfort of chair! Great Images, as always! I'm glad you there encouraging people! I've learned a lot from you!

  2. That's very words Robin. As you might know I began birding in earnest on 2011 although I have been interested in birds for years. What I most enjoy is being outdoors and meeting other birders like yourself.
