Pre-frontal coverage highlighted by Wood warbler

Heysham Obs
An early assessment on arrival suggested a single sheltered mist net and a bit of vis mig, followed by a quick check of the sea.  In the end, the constant threat of 'proper' rain saw the net being taken down after 30 mins and the rest of the area given a bit of coverage .

Thanks to Professor David Norman for getting back to me over yesterday's close-ringed Lesser Redpoll.  The reason David was familiar with the format on the ring can be found here  http://www.davidnorman.org.uk/MRG/Siskin%20moult%20extremes.htm 

It was ringed under the auspices of the International Ornithological Association (hence IOA on the ring).  The 11 refers to 2011 along with the deep blue base colour year-code.  The IOA were in contact today and will provide a town/village location (but obviously not the private address of the aviary) for the above bird.  If anyone wants to have a look at their website access the following link:

The conversation with the IOA secretary included problems they have complying with the letter of the law re-Lesser Redpolls.  Their legal documentation refers to Carduelis flammea pre-split (which is now, of course, the separate species Common Redpoll) and the legislation has not caught up, therefore in theory they cannot legally exhibit Carduelis cabaret = Lesser Redpoll.  Maybe it will be sorted just as they are re-lumped! Thanks to IOA for getting back to us and setting in motion tracing the origin of this bird

They also confirmed that last year's close-ringed Lesser Redpoll (caught 25/3/12) was of French origin with the last two letters of the WOF code = ornithologiste francais (or spelling thereabouts!)...........but were not sure what the 'W' stood for.

Office area vis 0545-0615

Reed Bunting - a very late individual flew high to the north
Goldfinch - 5 north
Swallow - 17 NE

Grounded
Wood Warbler - Singing male in the copse over the road from 0605-0610 only
Willow Warbler - At least 20 migrants, seemingly including at least three males (snatches of song).  Moved rapidly inland as is typical for this species at this time of year - almost certainly several/a lot passed through prior to arrival
Chiffchaff - one presumed migrant caught

North harbour wall/Ocean Edge vis intermittently 0620-0800
Yellow (flava) Wagtail - one north 0720hrs

Goldfinch - 6 north
No terns or any other seabirds seen in flight!
