Due to Covid restrictions we were not able to start with any
CES ringing until mid-June which meant we missed the first 4 sessions.
CES 5 : 15/6/20 (91
birds) Warm and Sunny. Claire and I divided the site between us and used
separate equipment. Off to a good start with 91 birds: Blackcaps, Reed Warblers,
Sedge Warblers and Cetti’s all with brood patches and plenty of juvenile birds.
An unusual Starling roost of about 500+ birds left the reedbed at 4:20am. A
male Great Tit was already in main moult. It was a strange start to the season.
CES 6 : 22/6/20 (100 birds) CES 6 was run the same way and was again an excellent catch of 100 birds and included our first Kingfisher since 2016 and lots of juvenile Great Tits.
CES 7 : 7/7/20 (101 birds) A magnificent sunrise with cloud and breeze increasing through the morning. With covid restrictions eased we had 4 ringers and had another good catch of 101 birds. The day was dominated by Reed Warblers and Sedge Warblers. Both species are doing well this year.
CES 8 : 13/07/20 (94 birds) Patchy cloud. We did not put up net A because there was a Song Thrush nest with 4 eggs half way along the net ride. We caught a second juvenile Kingfisher in the first net round and a third in the last net round, unfortunately Claire N missed both… Apart from that it was Chiffchaff, Blackcap, Reed Warbler and Sedge Warbler all morning with one or two Robins and Wrens and four Long Tailed Tits in moult. Two Oystercatchers flew over.
CES 9 : 28/7/20 (89 birds) Five Hobbies were hunting over the reed bed when we arrived and a Water Rail was calling at the end of net 1. The breeding season is still in full swing with lots of newly fledged Reed Warblers and six new Cetti juveniles, but a couple of Willow Warblers are a sign that birds are already on the move.

CES 10 : 2/8/20 (79 birds) The Song Thrush was still on three chicks along net ride A and we caught the female in net 2 on the last net round. Two Hobbies flying around. There are strangely very few mosquitoes this year. The Angelika is flowering and some Great Willowherb but the Orange Balsam that usually accompanies it is missing. Many juveniles now in post-juvenile moult although there are still plenty of very young reed warblers indicating that there has been an extended breeding season. One of the female Reed Warblers L942449 had been ringed in Aug 2012 so is 8 years old. Three juvenile Bullfinch were ringed and the elderberries are starting to ripen.

| Heavy rain in August had flattened the reedbed by net 1 & 2 |
CES 11 : 16/8/20 (54 birds) A misty, murky morning, “greech” we decided was the word. The reed bed had been flattened by the heavy rain over the last week or so, we could see right across to the causeway from net 2. Willow Warblers were moving through and we caught seven. There were also a few Sedge Warblers carrying fat and adult Blue Tit and Dunnock in main moult.

Here is a comparison of our commoner birds with last year’s catch. Adult
numbers were generally good but there were some big differences in breeding
success. It looks like Blue Tits did quite badly whereas Great Tits fared
better. We were unable to check the next boxes during lockdown so we won’t know what that was
due to. Blackcap and Chiffchaff did poorly compared to last year but Reed
Warblers and Sedge Warblers had a cracking year. We obviously had a Bullfinch
family on site and Cetti’s had another good year.
Thanks to all the ringers for their help and efforts this summer.
