No, I'm not talking
about the Yorkshire "Atlas Flycatcher" whose DNA surprised everyone,
this is about a female flycatcher I saw in Sicily recently.
First
impressions were a grey bird with a prominent pale collar and an
obvious pale rump. I knew Pied Flycatcher could show a pale rump but I'd never seen it so obvious on a Pied, and I don't recall seeing Pied with such a pale collar before either. This bird had a white patch at the base of the primaries,
bigger than on many Pied Flycatchers, and my suspicions turned to Collared Flycatcher. I
couldn't recall the finer details of what to look for in tail and
tertial pattern so took some photos and hoped I'd be proved right when I
got home. I had a nagging doubt - I'd seen Pied Flycatcher with this
much white on the primary bases and ideally I'd hoped to see more on a
Collared.
Well I'm back home now and I think my doubts were well-founded. Here's why I now think it was a Pied Flycatcher, not my first female Collared...
- White at the base of the primaries not extensive enough - not reaching beyond the primary coverts
- White on the outer tail feather broadest at the base (where it extends on to the inner web) and fizzling out at the tip - should be the other way round on Collared apparently
- Although it gave the impression of having quite cold grey upperparts I think that impression was influenced by the grey nape and rump - the mantle and scapulars look quite warm brown in the photos
- I don't think the upper tail-coverts don't look dark enough for Collared
- Tertial fringes possibly not narrow enough for Collared?

Now some questions:
- Are the contrastingly warm gingery ear-coverts significant for its identification?
- How normal is it for Pied Flycatcher to show such an obvious pale greyish collar and pale rump?
- Do you agree it's just a Pied Flycatcher?
- What do female Pied x Collared hybrids look like?
And now just for fun, here are a couple of straightforward vagrant male Collared Flycatchers from my archives:
