These images taken using a mobile phone, hand held through a telescope - with obvious limitations.

Hopefully they help illustrate how the birds can 'gradually appear' whilst the scanning observer changes viewpoint.

Luckily this location suffers no disturbance & therefore 4 of the birds are perched relatively openly, being observed relatively easily.

More often than not, starting by viewing the base of the roost trees can be a productive method to locate roosting otus.
Scoping, even from range, for tell tale signs of splash is a good system.
Working up the trunk, pellets may also be visible lodged in the branch network - as the season progresses, the branches imediately below the roosting bird can become very obviously white washed - this is often the best single indicator to aid locating obscured birds.

Why a species which relies on superb cryptic patterning to remain undetected, should leave such an obvious "calling card" beneath its daytime roost is a mystery......
perhaps those white marks help pinpint roosting branches when returning to the roost before first light ?


Countless hours of fieldwork in County Durham, primarily by a small but dedicated group of "owling specialists", has led to us confirming in excess of 100 breeding pairs of Long-eareds.


This week i obtained first account from a gamekeeper of a 'new' pair in a moorland edge location - there is certainly further scope to discover further breeding pairs..........

19 Jan 2010 - Barn Owls & Snow

A few recent reports of Barn Owls hunting over the snowy western side of Durham . . .



pic by Davy Johnson.

We're waiting for the white stuff to clear up a bit, before we get on with the nextbatch of boxes.

Pic below from Derek The Finch showing a bird with prey



it dived through that deep snow to catch its prize.

A couple of new BO pairs have come to light up there recently, with Mr Gavsterley locating a pair hunting yestday afternoon close to moorland edge @ 250/300 m/asl.
These are faring okay, but what above those further way out west & a lot higher up . . .
We found a Barnie roosting late in 2008 at 460m/asl (the highest elevated county record to date) - it made it through a couple of weeks of snow cover last year - not sure how it will have managed since mid December though . . .
