No show Leo

Dusk check at site with 2 pair Leo - single bird out hunting 17:45.
This was sole contact, no further sign, no calls, no display....

Its a worry.

Mid February 2017 - local update.

Long-eared males singing & wing-clapping at a couple of sites
Leo surveys his territory at dusk

The 1st Tawnies may well be on eggs - none checked so far
Little Owls becoming more vocal & more showy especially on the recent warm sunny days.
Our wintering Shorties continue their crepuscular activity - having been seen day flying on less than half a dozen dates.

Sunday, I stood with Mr Heron at dusk after a full 13 mile day out - he clocked a Barnie almost over our heads, with Little Owls & a silhouetted Tawny all from the same vantage point.

Tawny Owl Deep Chamber Egg Theft

Heres an interesting one from Spring 2015


22 March 2015
Found a New Tawny Owl nest site, with a clutch in a chimney-like hollow Sycamore.

pic from second visit

The bird came off on the initial visit, but second visit she never moved. (pic above)
The chimney-like cavity was a good 10-12 foot deep, with the clutch only a few feet off the ground.
Id imagined the young would be well on before they manage to climb / flap their way out of this one.... (spoke too soon !)

Second visit, the female sitting tight

3 April 2015
Third visit, - we were expecting young (cp other local nests) ,  Jack (nearly 10 y/old) was happy to go up, he wanted to see the bird sitting, but he called down that there was no bird & only 3 eggs & a hole ! - Three eggs & a hole we echoed - I couldn't wait to get up & see....
Jack shouted down "theres 3 eggs & a hole !"
An egg had indeed gone from the Tawny nest..... what a mystery...
We moved round to have a look at the base for the first time & saw the basal cavity for the first time... our cogs were starting to whirr...


The Evidence - Saw dust at the base of the cavity....

On closer inspection at ground level, it was clear the hole had been dug from underneath & the nest predated from below, with, presumably a Stoat (see him regularly close by) having come in the basal cavity & dug up through several inches of soft decayed timber to access the nest chamber.

The family pondering the mystery....

As we moved of we had a Consolation in the form of nice views of a Roe Deer (doe) while we talked through this unusual encounter.

Post Script - I meant to go back & try to fill it in with some rocks.... possibly a couple of years left in that stem....

Where sheep are sheep & men are....

Couple of hours at end of the day to check on some neglected Barnie roost sites on the Limestone.

Depending on aspect, Limestone nest sites can be unmistakable - years & years of splash stands like a white beacon, especially when under an overhang or otherwise sheltered from the elements.
Obvious white splash

Roost sites on the other hand can be much harder to locate - rock faces are littered with nooks & crannies - birds could be anywhere.........

NB: (A good tip when prospecting for any cavity dwelling owl (raptor or duck too) is to check for down feather caught in cobwebs.)

That was the case today, with only a few subtle clues on show.
A few small dots of splash didn't look like they were worth following up,
2 down feathers & tiny bit splash

but a check binoculars revealed 2 pale down feathers -  there you go.

Moving to the overgrown base of the slope, it took a while but I found a handful of large & quite recent BO pellets - almost there.
Barn Owl pellets - big & black

A scramble up through bramble & thorn got me 30' higher, where 1 very fresh pellet confirmed the roost as active.
looking down - NB telescope in top RHcorner.

From here, the otherwise hidden entrance to cavity held many more pellets & downy feathers.
roost cavity

Yes, a bit of a faff on, but far better than a stand & hope speculative visit as the light fades.

In fact id much rather do a bit detective work like this than hump a pair of ladders around checking nest boxes.

To end on a lighter note - I wasn't expecting to have this charge out at me :-
you know its a rough area when the sheep hide in caves !

Long & Shortage....

I can remember thinking what a stinker winter 2015 / 2016 was (after very poor Leo nest season) - I considered that to be the worst Owl winter i'd known....


Winter 2016 / 2017 has been worse.... The Worst....

I have never had many concerns about our resident Long-eareds - they were nailed on, Lots of pairs always there, no problem, guaranteed year round...

Not the case now after a series of poor breeding cycles...

So much so this season that I havnt daylight searched any more than 6 locations, with no more than a max of 3 birds... & switched to searching for Jack Snipe as the Bigg Luggs were proving so hard to come by.
For Example, a traditional location where ive had regular double fig roosts, including 18 in a single tree was blank this winter....
Things are picking up & pairs are beginning to call & display - though its obvious some sites are sadly vacant - the populations is certainly at a 20 year low - but, hopefully not for long...
