Light and easy

Pallid Swifts within Norfolk during November are regular but always a little contentious. They are never easy to distinguish from Common Swifts. Even photographs can be a little confusing and it’s not too difficult to inadvertently change a common to a pallid during processing. Time must be taken to watch the birds in a variety of light from various positions. It’s only then that distinguishing features can be clinched such as the dark eye, the darker saddle and underbody, darker primaries and leading edge of the wing that contrast with paler coverts and secondaries, the paler head and throat and the slightly shallower tail fork as well as paler feather edgings on the flanks. The feature of a blunter wing tip on Pallid is not as easy to distinguish as literature states and in my opinion varies from bird to bird. I guess it is one of those features that is dependant on it’s attitude in the air.

A message from Ben today stating he had a Pallid hawking along the cliff top at Overstrand saw me make a diversion from the shops in Cromer to the cliffs above the golf course. The light was immaculate as it frequently is in Norfolk and we were looking north to watch the bird hawking in front of the cliffs. Although relatively distant the bird’s milky coloured plumage was immediately apparent. However it took a while for the bird to come closer so the other features could be seen but in the end the identity of the bird was unquestionable.

Today’s Swift was in the company of a white rumped hirundine. Shame it was only a House Martin!
