Spring Spectacles –Waves of Warblers
For many bird watchers, this is the best time of year to reconnect with birds and the outdoors. For those with excellent vision (or a nice set of binoculars) and/or hearing, a good field guide, and a strong neck, spring is a great time to look and listen for the 50 kinds of warblers regularly occurring in the United States.
The energetic, often brightly-colored, sparrow-sized birds can be difficult to spot. Most male warblers become very vocal as they get closer to their final summer homes. While it can be challenging to spot a rapidly-moving warbler, with some practice it’s possible to locate and identify many species by their distinct songs and calls. In thick forest habitats where vision is limited, identification by sound is sometimes the only way to identify birds.
Most warblers are habitat specialists; knowing their habits helps birders target where to search and which species are more likely to be found in a given setting. A few species are ground residents, foraging and nesting from ground level to about 15 feet high. Others spend the majority of their time in shrubs and trees at the 10 – 40’ range, and some are tall treetop dwellers, causing many a case of “warbler-neck” when birders stare for hours almost straight up, trying to get a satisfying look at a five-inch bird at the top of a 70’ tree.
Yellow, Golden, Orange, Black…
If you live in the southeast, northeast or midwest (east of the Mississippi River), migrating or nesting warblers are easy to see in the right habitats and at the right times. There are fewer species in the central and western regions of the country, but some locations have good numbers passing through during the spring. To avoid going on a wild goose chase – unless you’re looking for wild geese – check the Web site for a specific national wildlife refuge before visiting to consider bird-watching reports, recommendations and upcoming bird programs.
