It seems as though the tercel has gone AWOL now and he has’t been seen since the 8th April – 4 days ago.  I saw the falcon almost constantly today – I was there for  6 hours – and she spent the majority of time calling and apparently searching for her mate.  It is not unusual for the tercel to keep a low profile and I would expect him to put in an appearance very soon.  I am confident that the falcon will produce another clutch of eggs but it will be dependent on the tercel’s part in proceedings.  I witnessed some very surprising behavior however.  The Kestrels were there again and at one point, with the falcon in the adjoining oak, the male Kestrel came in to mob her. It then landed next to the falcon and they both remained in the tree, next to each other for 20 minutes. Eventually the Kestrel flew off and the falcon flew back down on to her nest ledge. Later, the Kestrel flew on to the Raven’s nest and noisily displayed before gliding off.
