Early mornings continue to allow some pre-work catches, which had a odd mix of a couple of good Siskin days and a couple where early on in the day at least they were absent, though these two days produced a couple of oddities, on one are-trap of one of the first Blue Tits we ever did, T884385 on 15th which was first rung on 25/3/2006 and on the 16th a possible control Blue Tit, V954771, though we do have a group member that lives a few miles away that resided in Holland for a period that might be using up some old rings as the bird was a 5.
Totals were:
14/3 - Siskin (19) and one re-trap from this year
15/3 - Siskin (1) and two Blue Tit re-traps
16/3 - One Blue Tit re-trap and the potential Blue Tit control.
17/3 - Siskin (2)
18/3 - Siskin (15), Goldcrest (1), Dunnock (1) and one re-trap Siskin from 2009.
A round up of our bird ringing activities (all birds ringed under licence from the British Trust for Ornithology with schedule one authority where appropriate), birding trips and other wildlife sorties within the UK and whenever we get chance, elsewhere.

Garden - 13 Mar 2011
Well today turned into a bit of a Siskin day before and after the heavy rain. Denise had a Redpoll tape going as well, which seemed to help bring them in, plus a few Redpolls, but we have noticed on rainy days birds come into the garden to fed more frequently. The catch for the day was:
Lesser Redpoll - 4
Siskin - 26
and a re-trap Robin
Strangely and thankfully not a single Tit!

Weston Shore - 12 Mar 2011
A trip down to the Solent saw us with the Farlington RG team at Weston Shore at the reasonable hour of 7.45 to set up to two nets for hopeful, Brent Goose catch. After setting the cannons, all we had to do was too find the Brents that were nowhere to be seen as the tide was quickly rising. Fortunately 40 odd were by the sailing club and after encouraging them to move a little closer, a small group decided that the area in front of the nets was a suitable area to fed thankfully as time was running out quickly. A catch was taken with both nets resulting a decent catch which could have been easily a lot worse. The catch was 20 Brent Geese (12 new), 5 Oystercatchers (4 new) and two new Black-headed Gulls. The Oystercatchers were all colour ringed as part of an on-going project in the Solent and all the Brents were also colour ringed as part of a Dutch study (see http://www.geese.org/Ganzen/index.jsp).
Brent Goose processing and colour ringing. Because they carry two colour
rings on each leg they are not fitted with a BTO ring.

Garden - 6 to 11 Mar 2011
A few brief sessions in the garden, one briefly after the Sunbury Waxwing session on the 6th, and the rest due to the earlier sunrises before going to work on 7/8th & 10/11th, with the sessions on 7/8 th being joined by Gavin to get his first Siskin ringing experience and thankfully had a few to get a reasonable idea of the differences between 5 & 6s.
Totals were:
6th - Dunnock (2), Blue Tit and Goldfinch
7th - Robin, Blue Tit and Siskin (8)
8th - Blue Tit, Great Tit and Siskin (8)
11th - Blue Tit (2) and Siskin (7)
12th - Blackbird and Siskin (3)
Totals were:
6th - Dunnock (2), Blue Tit and Goldfinch
7th - Robin, Blue Tit and Siskin (8)
8th - Blue Tit, Great Tit and Siskin (8)
11th - Blue Tit (2) and Siskin (7)
12th - Blackbird and Siskin (3)
Goldfinch - 6 male
On the 10th we re-caught L605734 a 6 Blue Tit with a deformed bill that had originally been rung on 28/10/10 as a 4. The bill on the upper mandible was now 20mm (1mm) longer, the lower mandible was also longer. The bird was extremely waxy to the feel, probably to to preening difficulties and was only 9.9g, sadly possibly the bill defect was beginning to effect the birds condition and possibly life expectancy.

Sunbury Cross - 6 Mar 2011
The group did a third visit to Sunbury Cross with a view to hopefully catching further Waxwings. We mustered at 6.30am and got the nets up quickly as the birds started coming in and managed just one catch at 7.15, with a total of 11 birds, later followed by a single Blackbird. This allowed everyone present to gain further experiance of birds in the hand and we had at least 4 adults to compare with the remaining 7 5s.

Garden - 5 Mar 2011
With the Siskin numbers building up as they often seem to in the garden during March we tend to try and make an effort to capitalise on the increased numbers as they can be reliable for controls and equally it is good to try and re-trap some old friends. Today's catch brought in new Siskin (10), Dunnock (1), Blue Tit (6) and Great Tit (1), plus 2 re-trap Siskin and one Blue Tit. One of the retrap Siskin was V791680, fist rung on 28/02/2008 when it was aged as a 6F then. Older females appear bright/greener than certainly 5s.

Garden - 2 Mar 2011
This morning a nice new addition to the garden list, albeit only as fly overs, 4 Waxwings flew over as I got into the car to go to work, first picked by their trilling call. Nice start to the day!
