Parulidae Hybrids

The full hybrid index was compiled mostly using eBird and Avian Hybrids. Some hybrids listed by these sources don’t have photos or information online that I was able to track down, which is why some of these taxa don’t have individual sections in the guide dedicated to them. Contributions for these taxa especially are extremely helpful, but information on nearly all hybrids is lacking so any information or media is important. If you notice any errors or have something to contribute please leave a comment or send me a message.

Compiling a list of all known hybrids with examples is difficult for several reasons. Obviously I'm not able to obtain permission to embed all media of these hybrids on a single web page/journal post. This means I'm relying on countless other sites to continue to host said media for the foreseeable future. This will inevitably lead to broken links and lost media. Uploading to sites like iNat and eBird can hopefully prevent this.
