Cattle Egrets breeding on two RSPB reserves this year

Remember those Cattle Egrets that were discovered near Caulcott during the BOS short day count back in January?  They were part of a significant influx that culminated in the second and third records of successful breeding in England.  The first to be "made public", back in May, were a pair at RSPB Burton Mere Wetland.

Now, it has also been reported that five pairs have also bred at Ham Wall RSPB reserve in Somerset, raising at least nine young.  With a small colony rapidly established - at a site with several other heron species - maybe they can become a more permanent fixture as a UK breeding bird.  If they do, it may be just a matter of time before they spread northwards and start breeding somewhere in our area.

Cattle Egrets have a very wide distribution around the world and can provide a great spectacle, for example when they gather in large flocks before roosting in a favoured clump of trees:

Rushbeds Wood and BBS: Silver-washed Fritillaries and disappearing Tree Sparrows

I have a bit of catching up to do on the blog front, so apologies for recent inactivity! 
Yesterday morning I made my second and final BTO Breeding Bird Survey visit to my 1km2 survey site near Moreton Pinkney in south Northamptonshire.  This is the eleventh year running I have surveyed this area and I have now seen 70 species in total - normally I record about 45 species each year (but nothing new this year, so getting harder to add new birds!).  For most of the common species the numbers are quite consistent, the main change is that Tree Sparrow has gone from really quite common - 23 in 2007 and 14 in 2010 - to none at all either last year or this year.  The species showing upward trends have been Goldcrest, Raven (now breeds very close to the survey square) and Buzzard.  Some of the scarcer birds seen over the years have included Barn Owl, Willow Tit, Hobby, Cuckoo and Kingfisher.  I would definitely recommend participating - the BTO website enables easy data entry and you can generate really useful summary reports from your own sightings.  You are also making a significant contribution to the national scheme that is so vital for monitoring our birds.

Later in the morning, a trip down to Rushbeds Wood nature reserve in the Bernwood Forest area south of Bicester was rewarded with some nice butterfly sightings and some stunning flower meadows.  This was my first visit and I was really impressed with the woodland and equally, the adjoining meadows of Lapland Farm, all managed by BBOWT.   I had hoped to find Black Hairstreaks, but didn't manage to connect despite scanning some excellent looking habitat, however I did manage to find several Silver-washed Fritillaries and a couple of White Admirals.

Some good news for our local meadows from the Save Gavray Meadows campaign group.  Their tireless work to defend a cluster of meadows in Bicester from housing development achieved a notable success with the refusal by Cherwell District Council Planning Committee of the latest planning application from the developer, Gallagher.  However, there will be an appeal and no doubt this campaign will have to continue for some time to come.

Last week, on Wednesday, I continued my RSPB-organised wader survey in the Middle Cherwell Valley near Somerton (my third visit of the season).  Curlew continue to frequent the floodplain meadows in this area; on this visit one adult was feeding in a recently cut silage field.

This stretch of the Cherwell Valley is also good for farmland wildlife and is rewarding to visit year-round.  Common Poppies were particularly showy this time, with swathes of scarlet running through a couple of fields, especially near the margins.  Yellow Wagtails were gathering food from a large pile of manure, and Yellowhammers were singing from the tall hedgerows

Banburyshire and beyond: spring in full swing

April is a great month to be out in the field, which can make it even harder to keep up with the blogging!  Our resident birds are busy nesting, and some are already raising young.  And our migrants are arriving in ever greater numbers, returning to their favoured haunts to breed or just passing through on their journey north.  Many flowers and trees are looking their best too - meadows full of fritillaries and cowslips, copses and hedgerows bursting with cherry and crab apple blossom.  I've been able to spend a good amount of time out and about, mostly in the local area but with a few trips just beyond,  here are some of my highlights .....

Edge Hill Wood: Wood Anemones

Great to be out in the field today, calm conditions and increasingly sunny with really beautiful light in the evening.  Spring flowers are starting to look their best, especially Primroses and Wood Anemones.  I stumbled across a wonderful display of anemones whilst exploring the strip of ancient woodland that covers the scarp slope of  Edge Hill overlooking Radway, in south Warwickshire. 
Green and Great Spotted Woodpeckers are numerous here, as are Nuthatches and Goldcrests, you can also find Marsh Tits, whilst often overhead are Buzzards, Ravens and Red Kites.  There are plenty of big old trees with lots of dead wood, which is great to see as it is so important for wildlife, yet is often quite a rare sight in our local woodlands (all too often it is tidied away).

Slightly surprisingly, Marsh Marigolds are at home in the woodland too

The sparrow shots I took using my ipad to remotely trigger the shutter, enabling some better close-ups that I would otherwise be able to get.
I also called in to Balscote Quarry BOS nature reserve briefly, where a pair of Lapwings are nesting already, and a pair of Little Ringed Plovers are behaving territorially.  In a neighbouring arable field, a flock of Golden Plovers are still present, having spent the winter in the area.  Their numbers seem to be dwindling rapidly though, as they start to head back north (most likely Scandinavia) - I counted 360 last weekend and only 75 today.  Some are coming into breeding plumage and looking very smart indeed.
