Wknd 24-25 May

1st-sum GBB black-JYK05 was on Seton harbour wall on Saturday morning, ringed as a chick on an islet off Frederikshavn at the very northern tip of Denmark on 2 July 2013 (movement map).

3+4 Manx Shearwaters flew east past offshore. Seems "our" Common Scoters have gone to Musselburgh, just 14 RBM inshore, and only a handful of Velvets visible too (checked those of Seton prom but unlike last year they were all Velvets, Surfie habits must have changed). Only 32 Sandwich Terns on Gosford Sands Sunday evening, some courtship feeding still occurring, also 22 grey geese, presuambly Greylags, at Craigielaw Point which flew off north over the Forth.

Best sight of the weekend was an adult Peregrine with a decent sized kill, perhaps Feral Pigeon or Jackdaw, flapping vigorously as it headed on a course for it's nest, if I'm right a journey of over five miles, quite a feat. BWP states "In north-east Scotland, most prey seems to be taken within 2 km of nest-cliff, though hunting range may be extended to 6 km or more when ♀ begins to hunt too (Weir 1978a); in continental Europe, breeders may feed up to 15 km or more from eyrie (Glutz von Blotzheim et al. 1971)."

Monday - a Grasshopper Warbler reeling at dusk from a field edge south of Longniddry farm, no Quail heard there or Redcoll/Hoprig. Another Gropper still reeling very sparsely, presumably paired, on the bank at the west end of Blindwells main pond. Also on Monday Canada Goose broods b8 (small), b8 (medium) and b5 (large) at Duddingston, their numbers must be shooting up at a fair old rate now! Counts/range now ~ Greylag in 1988-94 tetrad atlas, we can probably expect a local population of many hundreds in 20 years time.
