Inverness: Aigas reunion

A few images from last weekend, when I joined up with friends to celebrate the thirtieth anniversary of our year spent together working as field guides at Aigas Field Centre, near Beauly, Inverness-shire.
On Saturday afternoon we ventured up Glen Stathfarrar, the valley was filled with huge flocks of Fieldfare, feeding voraciously on berry-laden Rowan trees and worm-rich pastures.  The flocks seemed to be everywhere, even high up above the mountains: thousands and thousands.  A single Golden Eagle patrolled overhead, also, earlier on, a Red Kite - a bird we would certainly not have expected to see thirty years ago.

That evening we had a great view of a Pine Marten attracted to peanuts next to our lodge  - they are now commonly seen here, but were still something of a rarity back in 1986.  On Sunday we stayed close to Aigas, wandering around the grounds including the idyllic small loch.  Fungi were much in evidence, nothing unusual but nice to see, especially the beautiful Fly Agaric.

Culworth: Dark Mullein and autumn colours.. and accentors

Definitely feels like a changing of the guard this weekend - with pretty much all of our summer migrants departed and  a few more of our winter visitors arriving, albeit in fairly small numbers.  On Saturday I drove though the Northamptonshire countryside between Wardington and Daventry, stopping in likely spots to see what was about.  Much of this landscape is arable farmland, most of which is currently bare ground following autumn harvest and before the emergence of the winter sown crops.  Gulls and corvids in particular are attracted to these fields, especially during cultivation or muck-spreading.  Lesser Blacked-backed Gulls tend to dominate, often with large flocks of Black-headed Gulls, however one area of farmland had attracted about 200 Common Gulls, by far the highest number I've seen so far this autumn, and a sure sign birds are moving in from the north and east.  While I was watching the gulls, three Fieldfares flew over, my first of the autumn - soon there will be hundreds in the area.  Another patch of farmland, just east of Chacombe, has attracted a flock of over 100 lapwings, actually quite a notable count for our area!  Two Golden Plover were also present with them, plus a few Skylarks, Meadow Pipits and Stock Doves.

Out for a run in the afternoon, Mark spotted a large plant with yellow flowers growing next to a footpath through rough grassland just east of Culworth.  It was clearly a species of mullein, so I returned on Sunday afternoon to take some photos - it turned out to be Dark Mullein.

I don't recall seeing it anywhere else locally, maybe I've missed it but I doubt there is too much suitable habitat for it either.  Red Kites were also on the wing in this area, patrolling above a pretty valley between Culworth and Eydon that is hidden from the road.  A Redwing flew over, and I stopped for a while to photograph the autumn colours.

Back-tracking to Friday, an hour spent watching the gull roost at Grimsbury Reservoir was rewarded with further views of two Yellow-legged Gulls, one adult and one two year old bird.  I managed to photograph the adult in good light with both my SLR camera and the iphone/telescope combination.

The beautiful Siberian Accentor hit the birding headlines this week, with the arrival of at least three in Britain (the first ever recorded).  This prompted me took look back at photos I took of Rufous-breasted  Accentor during a trek though the Sikkim Himalaya in 2010.  Their breeding habitat in Sikkim was juniper scrub at around 3500m, in this specific habitat they were quite common, but somewhat shy.  I didn't have such a good telephoto lens then either!  Interestingly, Alpine Accentors were migrating up towards their breeding habitat in the mountains, we encountered a small flock at over 4000m.  Of course we do have a resident accentor in the UK - the hedge sparrow.

Otmoor: Hornets and White-fronts

A relaxing and absorbing day spent wandering around Otmoor RSPB reserve with friends.  This really was the "day of the Hornets" at Otmoor.  Walking along the bridleway I first spotted three together crawling around on a fence post.
Seeing three together is not a common sight, so I look a few photos.  Then we realised there were many more the appreared to be feeding on the sap oozing from wounds in an adjoining Ash tree - several groups of two or three gathered around a good feeding area.  Realising we didn't really know too much about Hornets we quickly searched Google for the basics.  Apparently at this time of year they are busy mating.  There is a nice account of their life cycle here, which describes how on warm autumn days the sexuals (males and queens) swarm out to mate, collecting in trees near to the nest.  Presumably this is what was happening today, though we didn't actually observe any mating.

There was plenty of other wildlife of interest, including a small flock of  Redwings (about 40 birds) and Golden Plover (150).
Wildfowl are starting to arrive for the winter.  From the first reedbed screen we could see good numbers of Teal, Wigeon and Mallard, plus a few Shoveler and a single Gadwall.  A few dozen Snipe were also roosting or feeding on the edge of the muddy reed-fringe.
Large numbers of geese were grazing out on the wet grasslands, especially in front of the Wetland Watch Hide.  A small juvenile grey goose had me stumped for a while.  Is was noticeably smaller than the groups of Greylag Geese nearby.  Then, while scanning across the flock again I spotted the unmistakeable white forehead of a White-fronted Goose, with another slightly less well marked individual next to it.  Black belly stripes on both these birds were also distinctive.  They then joined together with the small juvenile goose and the penny dropped - this was a group of European White-fronted Geese, likely to be a family party, and freshly arrived from somewhere far to the north and east.

Earlier in the week I made another visit to Boddington Reservoir to see the evening gull roost, just in time to catch the last rays of evening sunlight, creating a stunning scene with the reflections of the Canada Geese in the calm water.

Upper Wardington: return of the Golden Plovers

With so many of our summer migrants now departed it was nice to welcome back for the winter the first small party of Golden Plovers, four birds to be precise.  I anticipate this flock will quickly grow in number over the next few weeks.  The plovers were some of the first birds I encountered on an early morning drive around the local farmland which was considerably better than anticipated, with Skylarks, Tree Sparrows and Grey Partridges all showing themselves.

The Golden Plover have returned to their favoured field on the edge of the village, a site called Top Dawkins. This autumn, the cereal stubble has not been ploughed (as normally happens), and it looks like oilseed rape has been directly drilled into the stubble.  At the moment this is good habitat for Skylarks - some birds even producing short bursts of song this morning - and Grey Partridge (four birds yesterday).

Further on, between Chacombe and Thenford, another large field had a group of thirteen Grey Partridge.  I think some, if not all, of these birds derive from released stock.  Sadly though the fields favoured by breeding Lapwings are already over ankle-deep with Oilseed Rape growth, so won't be suitable for them in 2017.  I am hopeful they may just move to an adjoining field, time will tell.  More positive and perhaps most surprising was a noisy flock of about twenty five chattering Tree Sparrows in a roadside hedge - the largest flock I've seen locally for a few years.

A late afternoon visit to Bicester Wetlands reserve was enjoyable, nothing too unusual but nice to find a Stonechat, plus a couple of Snipe and three Green Sandpipers.
Wildfowl numbers are also slowly building up, including about seventy Teal and a few Shoveler and Wigeon.

I've been out and about in the local countryside over the past three weeks, some long runs taking me off the beaten track.  There have been some nice birding moments -
  • Red Kites flocking around cereal stubble just after combining,
  • A huge flock of Meadow Pipits finding cover in autumn stubble (I estimated three hundred birds)
  • A single Hobby flushed from a dead tree 
  • A gathering of at least two hundred House Martins swooping about the sky searching for insects as they head south.  
I've also made a couple of visits to Boddington Reservoir where water levels are currently quite low, exposing mudflats and an island has appeared, much favoured by roosting gulls.  A spectacular rainbow was also memorable.
