Oxwich Marsh 5 November: firecrests on Bonfire Night

A couple of short sessions in fairly settled weather on 2 & 5 November resulted in a modest combined total of 65 birds.

On 2 November the wind was a light easterly, and on 5 November it was from the north and had strengthened to such as degree that by 10:00 we were packing up.

The catch was as follows:

The highlights were:

  • A first winter snipe captured just after the nets were opened on 2 November. The eleventh of the year to date.
  • A few more redwing, most of them adults based on criteria listed in Svensson (1992) - including the tip pattern of the tertials, the shape of the 1st tail feather and the presence / absence of retained greater coverts. We have now captured 36 in 2016, 
  • Another new Cetti's warbler, The ninth new bird of this species ringed since early October.
  • Seven chiffchaffs, It has been a good year for the species with 133 ringed (cross ref 99 in 2015).
  • Two new firecrests, bringing the annual total to four.

The first firecrest, a male, was not specifically aged, as the shape of the tail was inconclusive (rounded tails are more typical of adults and pointed tails of first winter birds). The second bird, a female, was carrying a reasonable amount of fat (score of 4 using the British Working Group system) and had a rounded, fresh-looking tail. We aged it as an adult. Pictures are below.

Many thanks to Heather Coats, Keith Vaughton, Emma Cole, Darren Hicks, Phil Mead, Lynn Watts, Sammy-Jo Pengelly and Natasha Dodds for company and assistance over the two visits.
