Latvia and the (Western) Edge of the Range
I want to know your ID thoughts about a 1cy Peregrine Falcon, photographed on 3rd October at Latvia. According to “Winter Book” it looks good for ‘Arctic Peregrine’ ssp. calidus = new subspecies for Latvia. Thanks!
Gaidis is writing from from Latvia. He’s the manager of birdinglatvia.lv – rare and interesting bird observation in Latvia.
A reply from MG:
Well this is lovely looking Peregrine. As you say, a bird in its first year. A 1cy.
It is not as distinct as some calidus but well within the ‘wake up and look at this’ range! It shows exactly the kind of features we want to be here if looking for vagrants. Right now.
The rather browner uppers, lots of pale about the head, specifically large pale cheek, rather thin dark ‘moustache’. A pale ‘nick’ under the eye trying to cut the dark moustache off. Rather large pale supercilium- bit broken up. Then check out that underpart streaking- YES! fading to thinner in the middle. What about the vent/undertail. Barring weak and reduced. All in all rather delicious!
How to record such birds?
I have seen similar plumage in similar latitude further north. The range to the north of this bird will appear in books as the edge/ overlap zone of nominate and calidus. I suspect more calidus pass through Latvia given the geography. Some of these will be travelling MONSTER distances. All such birds should be well documented as calidus and calidus-like records as part of the local avifauna.
Probably overlooked, I wonder what the real status of migrants/ vagrants passing through Latvia is?
I have lightened this first shot to show the underparts which were in shadow.
and then it lands
