Nice photos Andy and I agree with the identifications suggested.
I am a resident birder but by no means an expert on the finer points of plumage differences between striata and balearica Spotted flycatchers. All I can confirm is that balearica do appear much paler with more subtle streaking to the crown, warmer fringes to the tertials giving less contrast overall and little streaking on the breast.
When I visit the UK I am struck by how much darker striata appear with much more noticeable contrast overall. If I can find one that is, they are very common here. Striata do move through the island in spring and autumn but balearica stay to breed in huge numbers. Balearica arrive in mid April and depart mid September although a few linger into October. One was reported in Palma yesterday, sub species not known, so a few may overwinter. I hope this helps. Mike
