Beskrivelse: Still on the island for its second day, was found yesterday morning in the lighthouse valley and refund this morning in the slope of the Caldeira. Very mobile & vocal bird (singing many time).
After the split, it's gonna be the first 'Lanius borealis borealis' for WP.
Previous records:
Lanius borealis sibiricus Norway (November 1881).
Lanius borealis sibiricus Finland (March 2000).
Lanius borealis borealis Azores (October 2014).
Beskrivelse: Rough-legged Buzzard or Rough-legged Hawk?
After a half day walking until the top of Caldeira... At last a quite good view of the hawk.
Have attention to the extended black until the throat... It's a good potential to be a Hawk.
Interesting indeed!
A 1cy bird with pale eye in combination with diffuse tail and trailing edge to wing. A dark morph would have solved all the problems that are connected with separating ssp sanctijohannis from lagopus. The fact that it was seen in the Azores may be the only possible clue to it´s identity.
If I remember correct another presumed sanctijohannis was seen in the Azores in Oct 2001 followed by one seen in Isles of Scilly the same month and year, earlier in the month on the Isles of Scilly I guess? In the Netfugl gallery there is a bird from the Faeroes Isalans which looks like a dark bird.
Looking over possibilities for identification criterias (1cy in this case),offers no direct clues since varaiation is to be taken into account, most pale birds seems to be identical in this respect, at least on plumage features.
This one is more or less identical to This oneAnother setA few more - mixed ages
Just a few thoughs.

I see your point, Jan.
The Corvo-bird does however strike me as a little dark for a european Rough-legged. It seems quite streaked on the upper neck and the dark belly extends almost to the head. I am not an expert on the sanctijohannis-subspecies, but these features are not commonly present in european Rough-leggeds. At least it might be an indication of it being a hawk rather than a buzzard?
I am of course very uncertain and my mind is surely clouded by my very strong suspicions that Roughleggeds on the Azores aren't exactly unlikely to be sanctijohannis...
Sebastian,
as mentioned, the fact that it was seen in the Azores could of course be a strong case for sanctijohannis.
I was mearly consentrating on the possibilities for a positive identification, which seems to be very difficult indeed. I´m not aware of any study that presents such information. Something to dig into.

Lagopus Buzzard or Hawk on Azores ?
___________________________________
I tend to follow JAN and SEBASTIAN re less
conspicuous dark hind wing-trail and more
extended dark around head, than in most
juv. European lagopus.
Further, Eur. lagopus migrates South. It
is scarce in the UK (Beaman et al.),
wintering next to the North Sea, only
(Malling Olsen map in 'Rovfugle').
Going further Southwest it is NOT recorded
for Madeira and Canary Isl.s (Avibase).
So, Presumably a sanctjohannis Hawk?
PS: Stragglers may break patterns, like the
Wrn Marsh Harrier recorded in Caribia.

Mørkt omkr. hovedet og mgl. mørk vingebagkant
synes ikke så typisk for Europæisk juv. Fj.våge,
jfr. JAN and SEBASTIAN ovf.
Den trækker mod syd. Er fåtallig i UK og er
ikke rapporteret fra Madeira el. Kan. Øer.
Så formentlig nordamr. sanctijohannis lagopus
(= Hawk)?
