I watched this and another bird feeding close to each other at Pinhal golf course - neither made a sound!
By the way, and not doubting Lou at all, the best "feature" for clinching Short-toed Treecreeper are the calls and song - its a very vocal creature and very different sounding than Eurasian Treecreeper.
of course it is. but is you have a photo the best trait is the all white outer border to alula for STT, but only about half of them show it...(plus if the wingbar is well visible - no step in it).
It does happen - unobliging of them!
Please don't take this negatively, but if I was in the Algarve for a week I wouldn't bother with golf courses - unless I was stuck there with no vehicle maybe. If you go north just some 20kms ish - say along the road to Barranco do Velho you will hit very large areas of Cork Oak woodland where all the Algravean woodland type birds are easy - and many more of them than on the coast. Subalpine, Dartford and Melodious Warblers, Iberian Chiffies, Nightingales, Rock Bunting, Golden Oriole, Ib Green and Lesser Spotted Woodpeckers, Short-toed and Bonelli's Eagles (the former easy), Cuckoo and much more - anyway, just a thought
many STT don't show it, they have a dipped in white tip of the alula similar to eurasian treecreeper, but some (i don't know the percentage) brachydactyla have these white borders along the "front" edge of alula, sometimes not going way up, sometimes they do, like in this individual, and if it's the case, this is diagnostic for short-toed.
That said, I saw a lot of great birds and saw some blue sky and sunshine and I'm now determined to go back.
All good stuff, the area you were in is "completo" of Crested Tits, not always easy to find and absent from many areas.
You mean, "cheio" :t:
In any case you don't need to worry about Eurasian in Portugal. In the Iberian Peninsula it occurs only in northern Spain where it's sedentary (only non-relevant altitudinal movements); here's a distribution map.
2. ST Treecreeper (only one recorded in Portugal)
Damn.....once a year I make a terrible mistake in Portuguese and it has to be on here :-O
If I'd been chatting casually I wouldn't have said that.
22 years here and 13 in Spain...messes with the neurons!
