CES Sessions

CES Norfolk Broads


CES 5 (21st June)
The longest day was definitely not the best day and the day also finished with a washout. Despite good conditions early on, overcast and still, the birds weren't moving (or weren't there!) A total of 7 birds - a few Sedge Warblers, a gropper, a juv Robin... Rubbish!

CES 4

A narrow window of good weather saw the wind drop to acceptable levels and a trip to our CES in the Broads. The weather was too good really with sun glare on the nets from about 7am. Catches were about as expected or slightly lower than in previous years:

A better day at Waxham

Following two flunks at Waxham over the past few weeks (catching about 5 birds a trip), yesterday was much more successful. As well as quite a few new birds it was nice to get a good number of returning willow warblers and whitethroats caught in previous years. We also spring trapped a wheatear and a nice male stonechat. While attempting to spring trap wheatears we also found this nice juvenile Pallid Harrier flying over the ringing site!

Total 36 new (19 retraps)

More Horsford and more swans

An in the field update from Horsford...

1 Goldcrest
5 chaffinches
2 Bramblings
1 wren
And a load of tit.

So far

At Whitlingham yesterday we again failed to catch anything other than those pesky swans, 10 more before we ran out of rings.

Horsford session

A fairly average session at Horsford Woods was brightened up by a stunning male Sparrowhawk and another Brambling.

Swanning Around at Whitlingham

A few members of the group went down to Whitlingham CP to ring some wildfowl, unfortunately nothing was playing ball except the swans. But they did well and caught c.20 new swans as well as a few ring-reads. A couple of weeks before a couple of us also caught 2 mallards, one new and one retrap. 

Recent sessions at Horsford Woods have been quite good with about 120 birds last Sunday and probably approaching 80 birds on Thursday. Mostly tits and chaffinches with highlights being a couple of bramblings and a redpoll.

Ringing sessions over Christmas and the New Year

10 sessions spread out over the Christmas break saw a total of 233 birds caught, including a wintering Blackcap, a Redwing, and a "close ringed" Goldfinch - as close rings can only be put on birds when they are a few days old, this individual was probably a captive bird that escaped. 

There were of course plenty of the usual birds, Great tits, Robins, Long-tailed tits and Blue tits galore. 

This catching effort was mainly for Emily's mini-project looking to see if different brands of mist net differ in a) the number of birds they catch b) the number of birds that either see the net or c) the number of birds that 'bounce' (fly into the net and then fly out of it again). Provisional results suggest no significant difference, which is good!

More pied wagtails

Thursday afternoon saw a few of the group attempting to catch a pied wagtail roost that had been building to over 500 birds in recent days. The birds had been using two or three clumps of trees so the key was selecting the right one. we set up three nets- a double height (8shelf) 30 in front of one roost tree and some around one tree. the flock dithered and  a few decided that our trees would be the best for the evening and we caught 10% of the flock. 58 birds in total- including 2 white wagtails and 2 birds wearing rings.

The ringed birds were from a roost 2.9 miles to the south east. the first ringed 11 days previously (where Dave and Will caught 5 birds after running around a busy petrol station with nets(!)) and the other was from this same roost ringed earlier this year. The sex ratio was even and there were approx 80% juveniles. All birds were roosted overnight in boxes (to save bending tails in bags) and released at first light the following day. Hopefully the roost will stay in the same place and we can try again.
