Warblers ​Parulidae

​about warblers in nw ohio
The New World Warblers or Wood-Warblers are renowned for their bright tropical colors, intricate songs, and lengthy migration paths. Considered neotropical migrants, "our" warblers breed throughout various habitats in the US and Canada, and winter from the southern US to the tropics of central South America. 

The migrational timing of each warbler species is heavily influenced by whether they are making long-distance flights or short-distance ones. Their arrival to the lake shore is predictable within a few day period as day length is their driving factor. However, weather systems do play a role in hastening or delaying their flights. In spring, intense warm fronts early on in songbird migration can also produce “overflight” birds - species that typically nest farther south of Lake Erie or Ohio, but overshoot their intended destinations while caught up on warm southerly winds.   

While warblers can be found nearly anywhere during migration, they tend to accumulate near the shores of Lake Erie, and move to lower areas within the vegetation where they are more easily viewable. Due to the number of species and their abundance during migration in Northwest Ohio, warblers comprise the bulk of BSBO’s songbird banding data, resulting in detailed timing of arrival, peak movement, and departure for most species.
