Early winter bird surveys 2016 (Part 2)

North West Zone grasslands

The survey start-off was signaled by a group of 9 Pied Wagtail, which must have just emerged from their communal roost. Plenty of Reed Bunting and Wren were calling around the River Mole reed beds, and the occasional Song Thrush giving a high-pitched 'tseep'.

After yesterday's survey Snipe joys, this ominous pile of Common Snipe feathers is a bit of a sorrowful sight. Still, there is a good population around at the moment and the Sparrowhawk (presumably the culprit) has got to feed too.

We stopped in our tracks as we got closer to the reed beds, scratching our heads over this one call...

For a moment there we couldn't put our finger on it. However, later on and further downstream, we heard the more familiar, squealing cry...

Water Rail is the weirdest thing you will hear along the River Mole (except maybe for Tom Forward's imitation of a Water Rail).

A pair of Common Buzzard called to each other, one gliding towards the woodland with a Carrion Crow in wing-flapping pursuit. On the far side of the river, along the woodland strip, we scanned the gorse and bramble scrub for any movement...
   Luke then spotted a new species for the Gatwick surveys!

Stonechat (Saxicola torquata) male. RSPB

Stonechats are a stunning little bird, slightly smaller than a Robin. Its name comes from the call which sounds a bit like two pebbles being bashed together. The pair we saw are probably temporary winter visitors to our sites.

A scatological interlude to look at some mystery poop...

Too small for Fox, but containing lots of fur... A Stoat or a Mink perhaps?

Mistle Thrush made their machine-gun calls as they shot past overhead. Fieldfare were the loudest though; I love how they sound on the verge of hysteria.

Fieldfare (Turdus pilaris) RSPB

In the north of Brockley Wood, Chaffinches were calling loudly; it makes a nice change as we are usually a bit light on finches here. A flock of Redwing were busy in the understory and a Coal Tit called from the canopy.

As we rounded the bend on the river, two Roe Deer stood motionless only meters away. Just a little further along, the gang caught a view of a top predator - Sparrowhawk! Unfortunately, I was too busy predating on rich tea biscuits and missed it.

Towards the end of the transect we were closer to the tree line; Ring-necked Parakeets started up their cry, disturbing another Common Buzzard. A lonely Little Egret took off downstream in lumbering flight. Although we didn't find Katherine a promised birthday Kingfisher, we did get a lovely Grey Wagtail zip along the river and land up next to us. 

   We start with wagtail, we finish with wagtail.

Common Snipe (feathers)

Early winter bird surveys 2016 (Part 1)

Land East of the Railway Line: December 8th

Dawn breaks over the Gatwick Stream, and Tom Forward is about to have a date with destiny...

Actually, the date is with a Snipe, but this is not just any old Common Snipe (although we did see 7 of those); it's a little bit scarcer than that. He wanders along the wet flushes, keeping out a sharp eye...

A sudden burst of wings from the ground and it's off like a shot - a Jack Snipe! Another new record for our bird list at Gatwick.

Jack Snipe (Lymnocryptes minimus) RSPB

Common Snipe (Gallinago gallinago) RSPB

Much quieter than Common Snipe, the Jacks have a shorter bill and are a shorter, dumpier bird in general. The Common types will shoot off up into the air before you can get close, but Jacks can hold on until you almost step on them, then dropping onto the ground again after a short, low flight.
  A small flock of Meadow Pipits bounced past us through the air, and a Grey Wagtail descended rapidly down into the river channel.

 

Our next new discovery for this site is a Barn Owl roost in our 'Little Owl-Oak'. Not sure if the little-er owls would think much of their new neighbour....

Poking our heads over the bank of the Gatwick Stream by the sluice gates, and were surprised to see a dark, sleek mammal gamboling in the water. American Mink are insatiably curious and this one actually came towards us, then hid in a small clump of rushes to check us out.

Not much of a photo of course.

Dashing back over grasslands to the next transect, and we were stopped in our tracks by a pair of Kingfishers zooming low over the grass. Although strongly associated with water courses, they are known to sometimes cut corners and even head into woodland habitat to do so. Hey, I would too!

Into the woods and a flock of Redwing were busy foraging in the understory. Winter thrushes vary what height they forage at depending on available food source. Towards the end of winter they feed more on the ground.

More white-wash beneath a mature oak - favored perching point for a Common Buzzard?

A Song Thrush sang from a distant hedgerow. A Wren and Robin were also in song; only a few birds do this through winter.
   At Dunnock corner, there were constant loud calls which signified the usual debauchery. They always seem to get louder in winter, kind of like my own family. I guess domestic drama helps to keep small birds warm. I still get Dunnock and Kingfisher calls mixed up, which after 4 years of these surveys Tom F. must be getting fed up with.

Through the woodland strip and out into Lower Picketts Wood, mixed flocks were abound of Long-tailed Tits, Blue Tits and Goldcrests. We checked a little closer through the binoculars but sadly couldn't turn any of them into a Firecrest. At the end of the transect, our trusty Treecreeper finally called.

The final species count for the morning was 33 (not 34, as I only recorded Common Buzzard when I returned to site at the end of the day):
