I live in South Florida, USA, which is on a migration flyway. We also have many released caged birds and, unfortunately, a thriving black market in tropical birds. Our area is semi-rural/wooded. At my backyard feeder, I saw a bird with white body, black wings (can't remember if tail was black or white), and a black head with a small black crest. It was about the size of a jay or larger woodpecker. It was catching mosquitoes on the fly. The closest resemblance is to a European Mynah, but the body was a little longer and again, it had a black crest, or a restless flycatcher, although it had more white, I think. The bill was black. Neither the European mynah or the restless flycatcher are native here. Can anyone help? Thanks in advance.
