Corner Hall Offices

Whilst at work at Corner Hall offices today I noted the following...

Just before 9.00am the PEREGRINE was nearby at it's BT roost.
At 9.20am a SKYLARK flew over E.
2 CHIFFCHAFFS were in bushes across the canal from B&Q, of which one Juv. seemed to be practising singing.
A ROBIN was also "singing" a scratchy song - maybe one of this year's birds.
A GREY WAGTAIL was beside the canal.
2 JAYS were commuting between Two Waters, Corner Hall & Boxmoor.
c.22 HOUSE MARTINS flew over W. (Alot of movement W it seems as I noticed Phil Tizzard reported 160 going W between 7.00am & 8.00am in Stowe, Bucks, & Mike Russell reported yesterday well into the hundreds heading W between 6.45am & 7.45am in Stopsley, Beds.)
A Juv. MUTE SWAN flew S high over.
There was no sign of the Peregrine nearby at its roost at 11.00am when I passed.
At 12.00pm a MEADOW PIPIT flew over.
At 1.30pm a GREY HERON flew over high S.
At 4.15pm, nearby, up to 100 STARLINGS were in a group of smaller flocks wheeling about near the BT building & landing on aerials.
At 16.50pm a Juv. MUTE SWAN was circling - possibly the same individual as earlier.
