Least Flycatcher
Empidonax minimus

The Least Flycatcher is a bird of eastern North America, but they nest in the northern USA as far west as Montana, Northern Idaho. Further north, they make summer homes from eastern British Columbia, to Canada’s Maritime Provinces. We can also find them in the northern tier of the USA to the east coast. When the season for raising babies ends, most of them migrate to southern Mexico and Central America. They are the smallest of all North American flycatchers.
Taxonomists regard the Least Flycatcher as monotypic (i.e. there are no subspecies).
Many bird species seek isolated nesting locations, far from other members of their species. But these birds choose to nest in clusters or groups, with an approximate distance of 150 to 200 feet between nesting pairs.
I met my first Least Flycatcher at Little Lake, Alberta (Canada) in 2005 during my expedition to Alaska. I followed the meeting less than a week later in Fort Nelson (British Columbia). I would not see them again until I found myself in south Texas during spring migration in early May 2021. I met them during spring tours of Canada in 2022 and 2023. When I returned to south Texas for the 2022 fall migration season, I enjoyed their company once more on South Padre Island.

Least Flycatcher(Empidonax minimus) |
Description: The primary (wing) feathers seemed right for a Least Flycatcher, and the head shape seemed better (more rounded) than the Acadian Flycatcher. It’s hard to tell them apart. It was a bright Sunday on South Padre Island, and I stayed over 9 hours. I started the morning with an hour at Sheepshead Sanctuary and drove to the Convention Centre for the rest of the day, and met a couple of birds new to me. |
