The Whitethroat - A welcome Spring arrival, (using the term Spring loosely this year of course.)
From a photography point of view, its a case of "Now you see me, now you don't".
Quite infuriatingly it will sit in the middle of a hedge or more often than not, keep to the opposite side of the hedge to where you are and sing and chatter away. You get the general impression that he is laughing at you. Just occasionally it will hop into the open or partially in the open and take a quick look at you. If you have the camera up and ready you may just be fortunate to get off a couple of shots.
The Sedge Warbler - Equally as uncooperative for photography purposes another Spring arrival that will sit in the middle of reeds or dense waterside hedgerow and chatter away out of sight.
