A quick round-up

Yet again I've left it for a few weeks without a blog update. This becomes more of a round-up then than anything else.
Starting with last Saturday (25th July), I headed over towards RSPB Snettisham where I had distant but tickable views of the Broad-billed Sandpiper. Sadly too distant for shots of any kind but I shouldn't be disappointed because there are probably those who traveled from outside Norfolk to see it and dipped. This is a very rare bird in Ireland (I reckon eleven or twelve records only? But don't quote me), anyway it was a lifer for me so well worth the trip.

On Sunday I had a nice living room tick as I watched a Hobby hunting over the meadows that run along the northern edge of the river Yare as it passes around Whitlingham Broad. A considerable number of Swifts were hunting at the same time so was it possibly predating these??

Work wise , its plant shut-down right now so quieter than the normally hectic days I have. With that I took Wednesday off and with some domestic issues taken care of, I headed up to Holt Country Park in the afternoon for some butterfly fun - before the season finishes. All in all I had a very successful day, with great views of White Admiral and Silver-washed Fritillary.

A little bit of 'gen' from the helpful lad in the visitor center and I was able to locate the pond where I eventually came across at least one female Silver-washed Fritillary of the valezina form.

Silver-washed Fritillary of the valezina form
Valezina females can be between 5 - 15% of the population in larger colonies within the species main range. A gene that finds expression only in the female controls this form of butterfly (See Butterflies of Britain and Ireland by Thomas and Lewington P.218 for more!).
So with those all that taken care of, a spot of lunch at the car and then off to Cley where I walked the east bank and scanned Arnold's Marsh. Plenty of Sandwich Terns, a few Common Terns mixed in. Also many Redshank, Black-tailed Godwit, Lapwing, Dunlin, Ruff, four Knot and one Ringed Plover.
I scanned the sea for Skuas but got distracted by three Little Gulls patrolling up and down along the edge of the breaking waves - dainty little things! I got a few shots before rain and cold got the better of me (only a t-shirt you see... d'uh!).

A few jars

Last Wednesday night I got the opportunity to join those fine people from the BTO as they continued with their survey of Nightjars in Thetford Forest.
Nightjars have been one of my favourite groups of birds for some time. Everything from Nightjars, Nighthawks, Potoos, Frogmouths, Owlet-Nightjars to Oilbirds just fascinate me. Whether its their cryptic plumage, nocturnal habits, the strange noises they make, the superstition and old wive-tales that accompany them or all of that! From Africa, Europe, North and South America, I have seen only nine of these species. I had to trawl through my photos archive but did find some old images in there.

In Ireland European Nightjars are now sadly a very rare breeding bird. I have been fortunate to see and hear them on breeding grounds in County Tipperary a few years ago and had a passage bird one evening near Little Island, County Cork but that's been it. Until I moved to Norfolk! Holt CP, Winterton Dunes, Dersingham Bog, Buxton Heath, Kelling Heath and Thetford Forest are well known locations for them (to name a few) and over the years with careful management and support they are doing well.
On Wednesday I joined with Dawn Balmer, Ian Henderson, Greg Conway, Justin Walker and several others as we searched for nests and after dark attempted to net birds and place, or in some cases recover, geolocators.  The nest searching through chest high bracken was exhausting (for a 40 something desk jockey like me).

Our group of five found exactly zero nests, the other group of five found three nests - all presumably second broods. As we later set nets up around the nest areas, I did see one nest - if you could call it that. Two brown speckled off-white eggs resting on a bed of dead bracken - very easy to miss indeed.

Justin and Ian set up two sets of nets and Dawn a third set. Hidden in the bracken, Dawn and I watched this third net for about an hour but the Nightjars refused to play ball. One bird bounced out of the net and another pair seemed to see it at the last minute and flew over it. It was pitch black almost so gives you an idea as to how good their night vision must be.
Around 11pm, Justin and Ian texted to say they had caught a male bird and were about to retrieve the tag from it and would I like to see it? No second invite needed - I stumbled along the forest path to where they were. They had already removed the geolocator and kindly allowed a few quick shots on my iphone.

Justin showed me how to hold the bird, I was amazed at how small it felt in the hand, a very narrow body probably smaller than a Blackbird. The long wings and tail presumably give it a larger appearance in flight.

To release the bird I held my arm outstretched, my palm flat and opened my fingers. The bird sat for a minute before flitting off into the dark.

With that it was time to do a net round and then pack up. I got back to my car at midnight, home to Norwich just before 1am and was up again at 6am to walk the dog - but I didn't feel tired. I think the thrill of the whole experience was still there.
My sincere thanks to Dawn Balmer for asking me along and to Ian Henderson, Greg Conway and Justin Walker for patiently answering my many questions about Nightjars and showing me a bird in the hand - one of my most enjoyable birding experiences in many years!
