Together the Blue-winged Warbler and Golden-winged Warbler form a species complex that isn't fully understood. Each species can breed with the other, and produce offspring hybrids that themselves can produce further offspring, leading to all kinds of variations in plumage. This unfortunately has lead to a competition that the Blue-winged Warbler is winning: it is "breeding out" the Golden-winged Warbler throughout much of its traditional range.
In this part we hear the Golden-winged Warbler's "Bee-buzz-buzz-(buzz)" song, which sounds more like buzzing than warbling.
This soundscape was recorded at MacGregor Point Provincial Park on May 19, 2019 using an iPhone with an Edutige EIM-001 omnidirectional microphone.
