Naturelog: 30th March

The Tarn

Spring is here and so a new recording season begins. Having had a break over the winter from any formalised recording it is time to begin again for Butterflies, Dragonflies and Bumblebees on my patch and for Birds at Eltham Park. So a bright March day saw me doing the first of my weekly walks around the Tarn.

An early surprise was a Stock Dove in the Garden as I set out to walk down to the Tarn. This is the first record for me on the patch and although I didn’t disturb it, the bird had disappeared by the time I returned. On the walk down to the Tarn, I recorded my first Butterfly of 2017 a Speckled Wood.

Arriving at the Tarn the usual residents were in evidence but as I walked around the lake there was little evidence of Butterfly activity. Apart from the overwintering species, the first emergers are usually the Orange-Tips and eventually, a pair flew past me at the east end of the lake.

Tracking back up the south side and doing the wildfowl count whilst also looking out for butterflies I reached the sluice gate at the south-western end when a flash of iridescent blue sped away from me across the Lake – a Common Kingfisher – the first of the year – it must have been perched somewhere nearby in the bushes and took flight at my approach. As I left to make my way back home, a female Brimstone butterfly flew lazily across the path.

It’s been a while since I saw a Terrapin here, but this one was taking the opportunity to sun itself.
