This morning we ran our first Constant Effort Site (CES) session of the year at Attenborough Nature Reserve. The aim of the CES is to gather data on the survival and breeding success of birds nationally, with the dates of visits, number and duration of visits, and number of nets all standardised so that any changes in the data are a result of bird populations rather than ringer effort.
We caught a total of 29 birds (four more than our first visit last year), with a good variety of species: 5 Great Tit, 4 Blackcap, 3 Reed Bunting, 3 Robin, 2 Garden Warbler, 2 Treecreeper, 2 Long-tailed Tit, 2 Chiffchaff, 2 Blackbird, 1 Wren, 1 Cetti’s Warbler, 1 Reed Warbler and 1 Dunnock.
The net rides were much drier than last year, and the weather was warm and sunny. We heard a cuckoo, and lots of Willow Warblers even though we didn’t catch any. A range of butterflies emerged in the late morning, we saw our first damselflies, and Josh spoiled us with homemade cake too.
