Few subjects provoke the ire in a roomful of birders more rapidly than whether or not to count introduced species. The ins and outs of what is “countable”, what is “established”, and what is still an exotic alien has reddened faces and clenched fists among birders for decades. After that comes the discussion of which state bird records committee is loosest or tightest in their approach to exotics. By then, former friends begin to disperse faster than the young of the year.
But in the end, that is not really what matters here. When it comes to counting exotics, I find myself more and more adopting an eBird stance. That is: count them all, do it as accurately as possible, and submit your data. In the end, the importance of this goes far beyond a mere life list. What matters most is the impact that these growing populations of exotics have upon our native species and the environment in general. Make no mistake about it, that impact is huge.

The amazing story of Eureka, the Western Snowy Plover, began with an unexpected event on Memorial Day weekend of 2017. I do quarterly surveys for Western Snowy Plover (Charadrius nivosus nivosus), an endangered species along the west coast of North America. We survey a 2.2-mile stretch of Huntington State Beach in Orange County, CA. With my teammates, Doug and Chuck, we’ve surveyed this beach every January, March, May and September for four years. Huntington State Beach is a crucial roosting and feeding area for Western Snowy Plover, and we see some on every January, March or September survey.
Surveying takes three of us because the beach is quite deep at about 500 feet from the parking lot to the water’s edge. Our team walks in parallel, zig-zagging down the beach to cover everything. Snowy Plovers, with their pale, wet-sand plumage, can be hard to spot. They make it harder by crouching down in little divots on the beach, hiding until danger is right on top of them. May is the boring survey because it’s the only time we don’t see the plovers on our beach. By May, the plovers have migrated to their breeding areas elsewhere. Continue reading →
