Marsworth - 5th December 2017 - A high net for Redwings

Weather: calm, dull, slight mist.
Ringers LL and CMS
07:00 - 10:15
Nets: 300'
Lures: Redwing, Reed Bunting, Corn Bunting

We have not been having much success this year with the Latvian Redwing tape lure, just one bird at a time so Claire and I decided to make a more concerted effort this morning. We used one of my North Ron "thrush" nets that have a slightly bigger mesh and nice big pockets and we set it high. We used five sectional poles on each end giving us a pole length of about 4.5m (15ft). We tape the top three poles together with some duck tape for extra stability and to prevent the top pole flying off when you push the net up. The first net round gave us a Blackbird and a single Redwing but the next time round as I approached the net a huge female Sparrowhawk dived down over my shoulder into the net, it crashed around a bit and in typical fashion got out before I could get to it. She flew off and sat in the trees close by - the seven Redwings in the net were obviously interesting her!! We had to take the net down as she would definitely have come back but we were pretty happy with a tally of eight Redwings. I heard Redwings flying overhead last night so I think they are still arriving in our area and today's birds were all juvenile apart from one, whereas the birds caught up to now have been mainly adults.

Wilstone - 26th November 2017

Nets: 260’
Weather:   Breezy and cold
JT, EM, JSJ

Well back to the bracing wind and cold of a late November day !
Both the new ponds are holding water well despite the low rainfall of recent months, I find myself almost wishing for it to pour down in torrents, but only at night on a week day. There is hardly any food for the the thrushes either and no sign of a roost. So four Redwings caught was a plus today, these birds all had the biometrics of european birds. No sign of Redpolls flying around just a small flock of Goldcrests. A retrap Cetti's female and a juvenile MarshTit were the highlights of the morning along with the cake.

Cobbler's Pit - 29th November 2017


Ringers: Lynne, Pete, Adam, Claire
Nets: 280'
Tape lures: Goldcrest/chiffchaff mix, Redwing, Treecreeper, Redpoll, Chaffinch, Marsh Tit, Long-tailed Tit

Cobbler's Pit is a small wood that is managed by the Chiltern Society. It has a large number of old Box trees as well as Yew, Ash, Elder and some Corsican Pines. Tring Ringing Group were invited to do some ringing at the site and we hope to provide the Chiltern Society with information about the birds there. We did a ringing session at the wood in December 2016, one in the Spring and we made another visit today.

The weather was very cold and the wind was in the north-east, but the site was sheltered. We used the same net rides as in 2016 for nets A,B and D. Net C we split into 2 x 30' at the woodland edge where we had a 40' last autumn and since net E has caught zero so far we moved it to a new location. (There was a debate over whether this now should be called net F but I have made an executive decision and kept the new net location as E!)

By 9am when the warden arrived to watch the proceedings we had only caught 4 birds, 2 Goldcrest, a Blue Tit and a Great Tit. But we continued to catch 3-4 birds per round and our final tally was 25. This is exactly the same as last year but with a different species mix.

The tit numbers were higher which is probably as a result of a better breeding season for tits locally. We monitored the tit boxes in the wood this summer and 37 Blue Tits fledged, I was hoping that we might retrap some of these but surprisingly none of the juvenile tits we caught were from the local broods.

The net down the middle of the wood that runs through some of the Box produced most of the Goldcrests (as it did last year) and the new position for net E gave us 4 birds including the Chaffinch and our first retrap, a Robin.

We failed to catch any Redwings although the tape lure did attract a flock of 20-30 birds that sat in the trees above the nets.

Nuthatch, Marsh Tit and Jays were heard in the wood and Raven overhead.
