A Throng of Bird Species

A Throng of Bird Species

By Terry Sprague

Terry Sprague is regarded as Prince Edward County's primary naturalist. In this excerpt from his contribution to Wind, Water, Barley & Wine, he tells about the phenomenal number of bird species found in the county.

Perhaps no aspect of our wildlife is more dynamic than birds. With interest in birding escalating each year, consequently there are more knowledgeable birders in the field today than there were a century ago, documenting changes as they occur. Lester Snyder’s faunal investigation of Prince Edward County in 1930 documented the occurrence of 225 species of birds. Today, the total is 351 species. Even with Snyder admitting that a "dozen or so species” may have been overlooked during his faunal investigation, to see the county’s bird checklist grow by more than 100 species in only eight decades speaks for the ability of birds to move out of their normal range and appear in Prince Edward County. Many have become regular visitors, with a good number having established themselves as breeding birds.

During this time, the cardinal was experiencing a northward expansion of its range and it was only eight years later when the first individual turned up at a feeding station in the county. Another showed up the same year at Consecon. Prior to that first sighting, the cardinal made its Ontario debut as a breeding bird at Point Pelee in 1901, Toronto in 1922, and in just 16 years had managed to make its first appearance in Prince Edward County. As recently as the early 1960s breeding was practically unheard of in the county, but today the cardinal is considered a common permanent resident. Other species of southern affinities that are becoming established here as breeding birds include the orchard oriole, northern mockingbird, red-bellied woodpecker and blue-gray gnatcatcher. Others, like the Kentucky warbler, chuck-will’s widow, white-eyed vireo, and summer tanager that are observed occasionally in spring are presumed to be migratory "overshoots”. Others that appear only sporadically like the 1901 anhinga of tropical and sub-tropical United States, varied thrush from the coastal regions of western North America, and the fork-tailed flycatcher of Mexico and South America, fail to share their stories of travel with us, their appearances adding to the thrill of the unexpected.

Another example of a success story is the European starling. The first county record of this introduced species came from Picton in 1925, after having been introduced in New York in 1890. Just five years later, when the faunal investigation was being conducted, the starling was found to be "one of the most common and regularly observed birds”. The introduction of the house sparrow had serious ramifications for established nesters like eastern bluebirds. A non-migratory species, the house sparrow usurped any available cavity sites early in the year, resulting in a shortage of nest sites when the eastern bluebird returned in the spring.
