Leith Hill, 18th February 2017

The Leith Hill massive, namely Matt P, Robin S, David S, Wes A and Stu C, assembled on the lofty tower roof for 2017's inaugural '[in]visible migration' session. It was a classic blinder of a Leith Hill Towerwatch, with a stubborn, soupy mist enveloping our view and simply refusing to clear by mid-morning, at which point we'd seen enough mist and cleared off ourselves instead. Single Crossbill and redpoll calls punctuating the murk were the sole rewards for our vigil, although there was plenty time for a good bit of birding banter/gossip. I took myself off for a walk on the heathland nearby, Duke's Warren, which was a bit more ornithologically infused thanks to a singing Woodlark, a Woodcock, two more Crossbills and 115 cacophonous Siskins.
