Flying and foxes

May saw a variety of highs and lows on the reserve; The most eagerly awaited highlight occurred on the morning of Saturday the 20th of May when the kingfishers successfully fledged from Hempholme Meadow.  A lucky band of photographers were present to record the moment at first light - Tony Simpson:
Dave Mason:
Unfortunately the much anticipated family line up on the twig didn't occur.  Instead they appeared to disperse in every direction.  By just after 6am 4 had left the nest.

However after most folks had left a further 17 fish were taken into the nest hole by 14:30 so there must have been one or more still in there.  Unfortunately these were never seen leaving - so we can say there were five or more kingfishers fledged, but will never know for sure.  However things move quick in the kingfisher world; by the Monday they were clearing out the hole, and by mid week were mating again for brood number 2 - Tony McLean:
We're now awaiting the next hatching - likely around mid June - so it begins again! 

Another species having a good year seems to be foxes - earths both on O reservoir - Paul Lyons:
And Hempholme - Thomas Breithaupt:
But not so great for all occupants.  Unfortunately the little ringed plovers have not faired so well; They were well on with incubating - doing a great job of defending their nest from all comers - Roy Vincent:
Pete Drury:
But the protective cage was undermined and the eggs disappeared from inside.  Clear evidence of scraping and digging could be seen around the perimeter of the cage.

They are perhaps the biggest loss (although still present and hopefully will attempt again); but conspicuous by their absence are the black headed gulls.  Most years the cacophony can be heard a good distance away but there is only one deep water moated island with surviving nests this year.  In spite of our best efforts to protect the marsh it would seem the foxes have learnt to swim around the defences - Jeff Barker (from a previous year):
The new islands and peninsulas whilst working great for the passage waders and necessary to restore the eroded original landscaping, allows a transit around the marsh once they've made landing - George Stoyle:
So unfortunately its not faring well this season.  A late arrival pair of avocets yesterday are unlikely to fair much better at that rate - Roy Vincent:
There's little that can be achieved at this time of year; so this winter we'll have to have a good think about this conundrum.  However there is good success on other marshes with lapwing and oystercatcher nesting next door, and the marsh has seen some good results on the spring passage - black-tailed godwit - Frank Moffatt:
Up to 4 ringed plover martin hodges:
Smart wood sandpiper - Frank Moffatt:
At the height of summer there's still some interesting oddments about.  Around 5 little gulls in recent days - Frank Moffatt:
Brian Colley:
But the most extravagant show off has been the great white egret - Pete Drury:
Dave Hobson:
Erich Hediger:
A useful comparison with little egret - Martin Hodges:

Many of you will have noticed the South Lagoon drained over this spring; We've been doing a lot of complex work with the water works and environment agency over recent months looking at the water flow through the site.   We've just started refilling ready for the summer season to keep south marsh topped up.  This will bring oxygen and nutrient rich water into the marsh to arouse the interest of the egrets still further - hopefully right under the hide.  Whilst its not always obvious there is a massive amount of work goes on behind the scenes keeping everything optimised for the birds.  Certainly the long staying goosander appeared to relish it:
Likewise a thorough inspection of the former D res hide has led to the demise of the old south lagoon inlet or 'cattle truck hide'.  Rotten legs versus use means this one has been taken out of service and given over to the wildlife.  The nest box lads have kitted it out with nesting boxes and bat habitat internally to see out its days. 

Again another mixed bag when it comes to vole eaters.  The barn owls appeared to be doing well - Tony McLean:
We'd been keeping an eye on them on the new camera set up and were hoping for chicks imminently:
Alas whilst the cameras were off air and after two days of heavy rain the eggs were lost.  Presumably the result of a hungry parent. 

Tawnies have faired reasonably well - again monitored on camera (although not connected yet) was a nest containing a single chick:
A few days later it had emerged into the open - Darren Smith:
The parents have seldom been far away - Pete Drury:
One chick is not a remarkable tally - and perhaps its not a good vole year? - despite the lingering short eared owl on the approach road - Martin Hodges:

Kestrels though seem to be doing well with the water works pair not far off rearing young - Josh Harrison:
Sparrowhawks are active around the site as ever - Roy Vincent:
Mandy James:
Marsh harriers bothering the marshes too - Brian Colley:
Seemingly a great success has been the sand martins at long last on the artificial wall - we still need to determine exact figures but certainly looks promising - Roy Vincent:
And Martin Lonsdale:
Swallows too have been very much interested in the new shelves in the reception hide - but yet to commit - Tony McLean:
A fine pair of linnets by Pat Hogarth:
Not popular with all the reserve's passerines - but a welcome barometer of its health for us are the cuckoos back in force again - cracking flight shot by Don Davis:
Breeding success too for the roe deer it would seem - Frank Moffatt:
A busy time in the roe deer calendar - its also rutting season for the bucks now too - Mandy James:
Don Davis:
All happening for marsh frogs too at the moment - Paul Lyons:
But you don't necessarily need a vertebrate to make an appearance - a few recent sightings of the cracking banded demoiselle around site recently - Martin Hodges:
Hairy dragonfly recording record numbers - Martin Hodges:
Common blues - Tony Simpson:
And small coppers - Pat Hogarth:
Moths are a whole tale on their own - best left to the on-going endeavours of Martin on his blog - having recently taken the list north of 645 species with some great endeavours. 
 
Just on the cusp of greatness are the bee orchids - first few emerging now - Roy Vincent:
 
To follow shortly will be full details of the upcoming 'Water works for Wildlife weekend' to mark the opening of the new hide. 

Before that though there is an invite from East Yorkshire Bat Group this week to monitor and learn about the 8 species found at Tophill Low.  This Friday the 9th of June at 9pm join Geoff Wilson to listen in and glimpse some of our residents like the uncommon nathusius's pipistrelle,  Free with standard admission, no booking necessary.

A matter of taste

It's been a few days since the last blog posting so thought we'd better have a quick update...
Star of the show and admired by many has undoubtedly been... the cracking grey plover in full breeding plumage here over the weekend.  Certainly in the opinion of the author at any rate given its a comparatively rare species for site and a personal reserve tick.  May sees the spring passage for waders moving north, often very rapidly so its not often we are treated to such showstoppers - Pictures Roy Vincent:
But taste is a personal thing.  Others took great delight in Monday's drop in brent goose - also a rare occurrence with the last confirmed bird 9 years ago.  A brief visit graced us on D reservoir - Roy Vincent:
And certain gull connoisseurs find great pleasure in today's courting pair of Mediterranean gulls - Karen Williams. 
And up to 240 black headed gulls at a time on the marshes at present - Maurice Dowson:
But breeding bird wise these have got to be up there - sand martins exploring the wall by Francis Bell:
We've yet to have a successful breeding attempt in this wall despite being a well researched design based upon many other successful walls.  Given my prowess I was somewhat dubious about being called in to oversee constructing a duplicate to the same specification three years back, up at Gouthwaite Reservoir in the Dales.  Suffice to say that has been near full annually since.  We put it down to general bird finickiness.  Some walls don't go so well; some do.  One of our more rapidly successful attempts was the kingfisher wall built back in January - and home to what in reality is the biggest crowd pleaser on site - Bill Eggleton:
There's undoubtedly thousands of pictures of these showy birds present at Hempholme Meadow at the northern end of the reserve.  Now that the chicks have hatched we feel a lot better admitting their presence. Don Davis:
Steve Smith:
Mark Holmes - apparently a nice pike here:

We've had salmonids, rudd and today a flat fish brought in as offerings.  The suggestion is that the chicks hatched around the 24th of April.  According to the stats this would suggest that the emergence date will be approximately the 18th / 19th of May - feel free to organise sweep stake as to exactly when the ceremonial assemblage will occur on the stick.  Please be courteous when viewing and photographing the birds and allow others a chance to view.

Its likely the first brood will decamp to north marsh as is tradition, followed by a strong likelihood of a second brood so we'll have this all over again!  We'll put the caveat on though that remember they are wild and subject to the rules of the wild - we'll not count our chicks just yet as there some shady characters about - egg rustling stoat - Bill Eggleton:
And egg rustling fox - Don Davis:
The woodland herons are a bit more of an enigma in their breeding.  Still ferrying sticks about we reckon there are 2 maybe more nests in this burgeoning colony - but we can't see in the tree tops - Don Davis:
Unfortunately not breeding in the reserve - but undoubtedly raiding it frequently are the marsh harriers - Brian Colley:
 Maurice Dowson:
We've been asked many times why the harriers haven't returned after their 2013 success.  The answer is a simple one; that spring was a terrible one (which incidentally put paid to the last sand martin breeding attempt) and as such the oilseed rape crops were stunted and barely out the ground by late April.  This year they were flowering at the beginning of April - its a perfect habitat for them and a great substitute reed bed. 

Undoubtedly appreciating the better weather rather than the snow last April are the little ringed plovers - currently scrapping it out in pint sized fashion on the southern marshes - Francis Bell:
 Martin Hodges:
And good numbers of common terns through - Karen Williams:
Hopefully a better year for breeding than last.  However an early dip was achieving the distinction of being the only water body in East Yorkshire to not bag a black tern last weekend.  Time yet...

Some other nice birds we did get included wood sandpiper and a smart little gull - Roy Vincent:

Other resident breeders doing well - grey wagtail gathering up food on D res wall:
And barn owls sat on the nest at present - Maurice Dowson:
Carol Toohie:
Nice to see this ugly duckling too - this rather scruffy little egret was re-habilitated last year after being found exhausted over the river and nursed back to health by staff at Peel Veterinary clinic Hornsea.  The ringing team happened to be present at the time so it was tagged and released - though never really looked too good for the following month until it disappeared:
A year later and this smart beast has reappeared - Martin Hodges:
It can't be fully read as yet - but certainly many digits match of those seen on the ring which is on the correct leg so it is more than likely the bird survived and has returned to the reserve.  They just need to get breeding in that heronry now...
 
This is as much as I have time to undertake at the moment - as ever there's so much to see, record and photograph at this time of year.  Lots more info on the blog, facebook and flickr - but far better get yourself out and find it for yourself!
