Not 5 but 6 !

Ormesby Kestrel site, very apt !

Last night (Monday) the Kestrels were visited again to ring the chicks (see last post ).
As the chicks were extracted  for ringing to our surprise the box contained not 5 but 6 chicks ! The adults have been seen regularly sitting on the nearby  bales and seem to be finding plenty of prey.

Still can't get them all to look !

Out of the 6, three were males, two females and one to small to determine. 

Male with grey upper tail coverts.

 Female with brown upper tail coverts.

Some more Swallow pulli and another Stock Dove pulli were also ringed. At another Barn Owl site 3 adult Stock Doves came out of the box and on inspection contained 3 nests, 2 with one egg the other 2 eggs !

We also had a Hobby hurtling past as we left the site.

Females gone?

It's been a busy few weeks recently, checking boxes takes a lot of time!
All the tit boxes are finally finished, they have done quite well this year. Blue Tits seemed to be on average a week earlier than Great Tits, this is unusual for us as its normally the other way round. Most fledged well and there seems to be a lot of young ones about now.
One box at Ormesby contained an unfortunate individual with a swollen head, the rest of the brood (9 others) were fine. We did check the box later after fledging and it had gone, so may have fledged after all.

Not looking too good!

We are now checking the larger boxes for Barn Owls and are finding that some areas are doing well  while others not. The Caister/Ormesby areas seem to be struggling while Potterheigham/Martham /Hickling areas are doing well.

The usual suspects have been found nesting, if Barn Owls are not present, Jackdaws and Stock Doves are all too ready to move in.

Fed up Jackdaws!

Two of the Barn Owl boxes have contained dead female Kestrels, both long dead, we assume they starved in the Winter. One was ringed and is a control EL44851 (any takers?)  On a brighter note we have at last had a pair of Kestrels nest in a purpose built box with 5 chicks present.

5 Kestrel pulli (one is camera shy).

The Barn Owls have been interesting to say the least,  no young have been ringed yet as they are too small at present.  Largest clutch being 2 young and 5 eggs, another having 6 young. Several have 5 eggs. Interestingly none of the boxes have contained any prey items, Gary has been collecting the pellets at all sites to try and find out what they are eating and what mammals are present in each area, this will take some time!

At four sites the females caught proved to be different birds from last year, so where have all last years females gone? Two controls have been caught so far GC68232 and GF65522, also a  retrap female proved to be a chick that was ringed  at another site nearby last year.

Barn Owlets

At some sites Swallows have been present and several broods ringed so far, these also seem to be a week or so earlier with some already on the wing, however others are still on eggs.

More good news at Horning was a nest of Spotted Flycatcher with 5 eggs, historically this has been our only reliable site for the species with 3 or 4 pairs breeding up to 5 years ago, but now has become quite a scarce breeder. We have not found any for a couple of years now, this year there may be 3 pairs present, fingers crossed!

Several species of Dragonfly have been seen on our travels; Black Tailed Skimmer, Norfolk Hawker, Four Spotted Chaser and Hairy Dragonfly. Butterflies have included Red Admiral, Wall Brown, Small Tortoiseshell and Common Blue.

Barton Demo 2011

We again attended the Barton Broad 'Go Wild ' day this year. It took place on Sunday 22nd May and was organised by The Norfolk Wildlife Trust.
There were several other organisations and displays present. The weather was dry and sunny but the unrelenting wind done us no favours. 

Mel sorting the picture quiz out.

Birds were few and far between, luckily for us Mel came along and organised a bird picture quiz that went down well in between birds and a prize was given to all correct answers! The younger attendees also enjoyed Arthur explaining the way we catch birds in mist nets, cuddly toy birds (supplied by Gary, much to his grandsons' dismay!) were thrown into a 20' net and then extracted, bagged and brought to the ringing table.

Dave doing what he does best....... talking !

Justin done most of the ringing until Sharon turned up and ringed the last 2 which included the bird of the day a Gropper. We did have a couple of more nets up this year and some feeders were put out in advance but due to the wind we caught about the same as last year. 21 new birds were ringed.

Thanks must go to Dave and Justin for cutting the rides, Dave again for putting the feeders up and Mel for the Quiz and photo displays.

Cuckoos at the crane

The crack of dawn really is early but it was at 03:15 that Justin and Paul arrived at our Martham site to put up the nets in anticipation of catching cuckoos that have been heard since end of April. Phil Atkinson and Chris Hewson from the BTO International Research team arrived shortly after. Justin with his trainer Paul Noakes have been helping Phil and Chris with a BTO project to track cuckoo migration by fitting birds with small (5g), satellite transmitter tags. Given that the additional weight that each bird can carry is limited for welfare issues the BTO had already decided that the minimum suitable weight for any cuckoo would be 115g. This limitation meant that more cuckoos needed to be caught to meet the required number of five for the project so Justin suggested that permission was given to catch birds at Martham.

The nets were erected, decoy cuckoo installed and tape lure played and shortly after the first male arrived and promptly perched on some scrub scrutinising the decoy. Fortunately it was at this moment that Tony drove up and the bird took flight straight into the net. A short sprint through long wet grass and the bird was extracted, brought back to the BTO vehicle and weighed by Tony. A smile announced that it was of a suitable weight and after Tony had ringed his first adult cuckoo the BTO team diligently fitted the harness mounted satellite tag.

Whilst the first bird was being processed another bird found the large mesh nets and Justin returned with a female. Sadly few female cuckoos are above 115g and at 101g this bird was duly ringed and released - a second adult cuckoo for Tony! All was not yet lost for before Phil and Chris had finished fitting the first tag another male had found the catching area and after several agonising minutes Tony was running to the nets to extract it. Justin ringed and weighed the bird and at 118g a second Martham cuckoo would be participating in this important research project.

In total 6 males and 2 females were present in the area with 2 males and a female caught - a good morning!

Lound Lakes Demo

Lound Lakes 

On Saturday 14th May we arrived at Lound Lakes for a ringing demonstration, the punters were already there on a dawn chorus walk, they arrived at our ringing station about 6.45am. The net rides had been prepared by Justin  a fortnight previously, Dave and Justin erected the nets on Friday night to save time on Saturday, this enabled us to open up at the leisurely time of 6am. 
The forecast wasn't brilliant, but we managed a good session with no rain. A moderate NW  made it a bit cooler than recent.

Arthur, Dave and Justin are in there somewhere ! Tony is about to release a bird.

We managed to catch 35 birds with 31 new and 4 (retraps), there was a good selection of species and enough birds to keep everyone happy.
 Tea and croissants were supplied by Holly and Claire , Thank you !

One of the stars !

Also seen were Common Sandpiper, Kingfisher and Hobby with a Water Rail heard only.

Justin informed us that he had found a Snake skin near to one of the rides during the week, this was 2 metres long and had a Python pattern on it !!!!!!! Fortunately we never came across the owner, however we did see a couple of Grass Snakes warming up under a tin sheet.

Looks like it is still digesting a recent meal.

RARITY ALERT !

We all saw something today that will go down in ENRG history, you had to be there to believe it ! Some of us still think we were dreaming, but thankfully Arthur has the proof in his pocket.

Dave actually handed over some money, he wasn't happy and didn't want to let go ! Hopefully he will get over it and be able to carry on, it didn't help that after the demo he went on to ring 48 Tit pulli out of his own pocket as well. 

Arthur doing his best to get the cash.

Nest Boxes

On Tuesday evening we Belatedly checked some Owl boxes, we have been waiting for the wind to die down!
7 Tawny Owl type boxes were looked at, which resulted in the following occupants 2 Jackdaws one with 5 eggs the other 5 small chicks, another Tawny Owl with one chick, Stock Dove with 2 eggs, One with a Grey Squirrel ! and the rest empty.

Jackdaw eggs

5 recently hatched Jackdaws, one is hiding !

An adult Stock Dove was caught exiting one box and was a new bird to ring. Gary also managed to net a Squirrel ! but luckily for us escaped before we were bitten extracting it.

At the Tawny box the adult female was caught and proved to be old faithful, a bird that was originally ringed 07/05/2007 and also retrapped 18/04/2009. It was good to see that she is still going strong. Apart from the one chick the box also contained the hind quarters of a baby rabbit that was bigger than the chick!

'Old faithful'

Barn Owl incest

It has been a bad weekend for mist netting, a trip planned for Saturday had to be shelved at 4.30 am, all because of the strong Northerly winds that continue to blow.     
Lapwing pulli were on the agenda for Bank Holiday Monday at Haddiscoe Island, unfortunately due to the dry weather at the moment there are no flashes of water and the grass is too long, so all this has had an adverse effect on the breeding attempts.
There were several pairs seen and a lot of mobbing going on, but no young were seen, only a couple of nests presumably with eggs.
Also as usual several pairs of Redshank, Oystercatcher and a Snipe were seen 'mucking' about, but nothing definite was happening.
 Also on the wader front were several Whimbrel, Bar tailed Godwits and a Common Sandpiper seen but no Avocet.

All sweet and innocent , Mother (right) and Son

The biggest surprise was to come when we checked a Barn Owl box on the Island. Both adults were caught coming out of the box and both were retraps.

On checking the ring numbers it was found that the female was previously ringed as an adult breeding in another box on the Island on 16/05/2009, no big surprise!

But when we checked the males number it was found to be one of the females young from that year, ringed on 11/07/2009 !!!! One egg was in the box,so now the mother is breeding with her own son !!!!!

The female weighed 415 grammes so was in good breeding condition, it will be interesting to see if anything hatches or if they are infertile.

Another Tawny Owl was checked at Lound and contained 3 pulli ready to ring, all doing well. The female was close by watching us.

A trip to North Norfolk on Sunday saw plenty of Green Hairstreak on Salthouse Heath amongst the Gorse bushes, always a superb insect !
