Rare Visitor: Ash-throated Flycatcher

Sometimes a bird will appear somewhere far, far from its normal range. These are known as vagrants. Although I think adventurer has a nicer ring to it. An Ash-throated Flycatcher has been staying at a town conservation site consisting of a bit of a farm, community gardens and walking paths. The farm is about 1 km from my home “as the crow flies”. But these birds breed in the western US and the edge of their range closest to me is in Texas and about 1900 miles (3000 km) away. I had to get some photos of a visitor who came almost 2000 miles to visit my town!

Ash-throated Flycatchers are regular, but rare visitors to the eastern US according to Cornell Labs. How does an 8 inch (20 cm) bird end up 2000 miles out of his normal range? I did a little research and there appears to be a few possibilities. Young birds can just get lost. Storms (we have had a lot of them this year!) can push them off course. And some research indicates that solar activity that disrupts the magnetic field can cause migratory birds to get confused since many use the field to navigate. Hopefully he finds his way back to Mexico for the winter so he can share his adventure with his fellows.
