A resume of the month of March and the first two sessions of April at Wilstone.
The first Chiffchaffs of the Spring: On the 25th March we
caught four Chiffchaffs, three were new and one was previously ringed as a juvenile at Wilstone
during 2017. As of the 7th of April we now have six retraps and eight newly ringed
birds.The two over-wintering individuals caught in the New Year have not yet
reappeared after the intervening cold snap, hopefully they have survived somehow. Several of the spring Chiffchaffs show signs of feeding on fruit trees
in recent weeks, see Jenny's photo.

Over these last few visits we have also
handled 19 Reed Buntings, two of which sported colour rings from Marsworth.
How will the clearances made last winter and the creation of
the new ponds affect the results of our efforts this coming year? The ponds have
already proved popular with Teal and Snipe, not to mention certain mammalian
species. Reeds should spread into the area between net rides 4 and 5, as they
have between rides 2 and 3, so improving conditions for warblers at the expense
of tits.
