Linacre Nestboxes - an update

I spent three and a half hours down at Linacre this morning carrying out the second check of the nestboxes. See here, for the details of my last visit. The number of nests had increased from 29 to 35, and included our first Mandarin Duck of the year.

Later in the day, Ray and I went back down to ring her. Whilst off the nest, we counted the number of eggs, so we could do a nest record for the BTO's Nest Record Scheme. I took a photo, and think I can count at least 29 eggs!! There were only 3 nest records for Mandarin Duck in Derbyshire in 2015 (the last year for which data is available), and only 48 for the whole of Great Britain and Ireland, so every record can help build up information about this species' breeding cycle.

The other 34 nests, ranging from N1 (just started), to NL (nest lined), were all either Blue or Great Tit, with the most eggs being a super clutch of 12! Last year, we had one Pied Flycatcher nest, so fingers crossed for one in 2017 as well.

2 other nests that were active today were one each for Moorhen and Coot. The Coot nest was the same one I'd seen on 11th April on the top reservoir, and the Moorhen was a new one, also on the top reservoir. It was about 1.5m up in a willow tree by the boardwalk. Hopefully, it should be safe from the dogs up in the tree! Unfortunately, I couldn't see into either nest to record the contents.

As well as nest recording, I also recorded some of the birds on and around the reservoirs. 2 Canada Geese were seen on the top reservoir, and the first Mallard ducklings (6), were on the middle reservoir. 1 Grey Wagtail was heard, an immature Cormorant was seen, and a pair of Mandarin Ducks were feeding around the bridge on the top reservoir.

Siskin and Lesser Redpoll were heard again, and Chiffchaff, Willow Warbler and Blackcap were all singing.

Wild Garlic was in flower, as were BluebellsGreater Stitchwort, Lesser Celandine, Marsh Marigold  and Red Campion.
