Classical Redpolls!

For more than a week now a group of 30-40 Redpolls have been visiting our garden and surroundings. It's a mixed group with both Lesser and Mealy Redpolls. Today I succeeded in catching one of each species. Both were classical examples of both species! Below of short photo study of the birds:
Lesser Redpoll (Acanthis cabaret), looks like a 1cy with a moulted GC9 (see arrow), male (hint of pink in rump)
 Mealy Redpoll (Acanthis flammea), 1cy male, note the 5 retained outer-GC and tertails
I would be happy with unstreaked undertailcoverts in combination with a white rump:)
 And a nice comparison of the two species!

Lanceolated Warbler! 4th record for the Netherlands!

I was awake in bed early this morning when I suddenly saw my phone lightening up: a call from Bram! ''I think I just caught a Lanceolated Warbler''!!!! Whaaaat? Seriously? He was serious... As soon as I could I alerted my dad and 45 minutes later we arrived at the Ooijse Graaf near Nijmegen.

The 4th Dutch record, the second ''live'' sighting of this species; earlier records were 2002 (one ringed along the Dutch coast), 1958 (found dead), 1912 (found dead). So an extremely rare catch!

Finger biters

Finger biters, not so surprising when you take a look at their bills. Both ringed at my CES recently.

Búho real

For almost a week, the Siskins were gone from our garden, but as the cold stayed (and we got some snow) the Siskins came back. On Friday several Siskins were visiting our garden again. In the early morning yesterday I opened my net in the hope of catching some more.

Due to the fact that I didn't have my laptop at home the last two weekends I failed to do an update on the Siskins. On the Sunday the 17th of March I caught the amazing number of 37 Siskins in our garden! 34 were new, 3 were retraps from early March. I didn't know I could catch so many in our relatively small garden, with a single 6m net.

So yesterday, Saturday the 30th of March, I tried again. And I was not dissappointed! I ringed 21 new Siskins, and recaptured 2. One recapture wasn't mine...! It was ringed by my trainer Hans, the day before (Fr 29-03) in his garden. His garden is only 900m away from ours, but still, a great recapture!

Catching (can you count all 8 hanging in the net?)

Then after some ringing we made a short visit to the Middle-spotted Woodpeckers near Hoog Soeren again. We had three males, showing well for a short period of time. Afterwards we visited my grandparents in Ruurlo, seeing quite a few Siskins and a Brambling in their backgarden.

And after a nice chat with my grandparents we went to Winterswijk to check out the breeding Eagle Owls in the quarry overthere. We were rewarded with lots of activity!

As soon as it got quiet the mother started feeding the two chicks (approx 8-10 days old). I'd never seen it before so it was great to see. As it got a bit darker, dad started calling in the nearby forest, making the experience complete! Wow!

Look at those eyes! Eagle Owl (Bubo bubo), phonescoped

Review of the year 2012: starting with Israel

As the end of the year closes in it's time to review this year! It's been a great year concerning birds, my two months stay in Israel being the definite highlight! Therefore I will start with a review of the two months Israel, followed by other top birding moments of 2012.

At the end of February I went to Israel to volunteer for 1,5 months at the IBRCE and for a week at the JBO. It was a great experience, learning lots of things about the passerines there - birdspecies I'd never handled before - and next to that, the raptor migration was impressive as well, with thousands of Steppe Buzzards passing by.

To start off with the typical migrants that stop by in Eilat:
 Cretzschmar's Bunting (Emberiza caesia). Many were present during the month March with up to 60+ at Ofira Park on one single occasion. All over the city and the IBRCE this species was seen. Ortolan Buntings arrived later, also passing by in huge numbers.
Rüppell's Warbler (Sylvia rueppelli). We observed and trapped many species of warblers. Rüppell's Warbler being one of my favourites! Over 100 individuals were trapped, an impressive number! This picture was taken in Ofira Park, where they were foraging out in the open. 
Barred Warbler (Sylvia nisoria). This is my other favourite warbler. Such 'bulky', large, sylvias are amazing birds to handle! And look at the eye...
Rufous-bush Robin (Cercotrichas galactotes). These beautiful bush robins arrived late March, early April. Too bad we missed out on the Black Bush Robins this year..
 Pied Wheatear (Oenanthe pleschanka), adult male
Cyprus Wheatear (Oenanthe cypriaca), adult male
'Vittata' Pied Wheatear (Oenanthe pleschanka), adult male

This spring was marked by an unprecedented influx of Pied and Cyprus Wheatears. They popped up everywhere and some eventually ended up in our mistnets at the IBRCE. Most wheatears were present just behind the IBRCE in the Date palm plantations. Identifying them in the field was quite a challenge, once in the hand it was much easier.. The second (well first one alive) 'vittata' for Israel was found on the 24th of March by two Dutch birders, Marc Guyt and Arjen van Egmond near K20.  It was my first Israeli twitch. It was a very nice bird, and certainly one of the Wheatear highlights for me. 

 Semi-collared Flycatcher (Ficedula semitorquata), male. While I was suffering from sinusitis and lying on my bed with a vast headache the boys woke me up, guess what we have!! They showed a beautiful male Semi-collared Flycatcher. A species that is not caught annually at the IBRCE (unlike this year with more than 10 being trapped). This bird made my sinusitis more bearable for sure... What a stunner! We also saw quite a few at the Date palm plantations behind the IBRCE. Up to 5/6 birds during one single visit.
Caspian Stonechat (Saxicola maurus variegatus). This surprise we found in the mistnet is one hell of a bird too! Nice white rump, T-shaped tail.. you won't get a Caspian better than this!

Crested Honey Buzzard (Pernis ptilorhynchus). Pictured above: the famous female that has been wintering in the Eilat Northern Date Palms for the past few years. The Crested Honey Buzzard was one my wish list, we first saw this female on 8-3, but I got very poor views of the bird, I couldn't tick it yet.. Then the next day we were extremely lucky to see the bird fly in between the two date palms. Normally we were only able to see it glide through the palm tops, having a very short observation. This observation however, was of longer duration! A few weeks later, we had an adult male Crested Honey Buzzard flying over the Southern Date Palms. First we thought it was an Osprey, then a Bonelli's Eagle and then: oh sh*t! Crested Honey Buzzard. Of course one of those moments during which you've left your camera at the ringing station..

Continueing with the Nightjars:
Egyptian Nightjar (Caprimulgus aegyptius), a memorable night we had in March at Yotvata. We observed several Egyptian Nightjars and were able to ring two of them! Other than the Egyptians the evening trip held lots of Stone Curlews, a Pharoah Eagle Owl, a Barn Owl and Jackals not to forget the Pallid Harrier we saw hunting on hundreds of Short-toed Larks in the evening!
European Nightjar (Caprimulgus europaeus). On the last day of my stay in Israel we ringed two European Nightjars at the JBO. We'd caught one in Eilat too but catching European Nightjars in the middle of the city of Jerusalem is much more special...
Nubian Nightjar (Caprimulgus nubicus). This was a very special night. After a long drive to the Dead Sea, resulting in, eventually, a broken car, we had a crazy night with first Blue-cheeked Bee-eaters catching insects above our head and then as it started getting dark displaying Nubian Nightjars. To see (and ring) this endangered species was incredible!
Hume's Owl (Strix butleri). Together with Nubian Nightjar, these were my two target species for my trip! Walking in the dark in a deserted wadi, only light coming from the stars and moon and then... a singing Hume's Owl, showing off on a cliff just above our heads!
Scops Owl (Otus scops). Cute little owls, a pleasure to catch!
Common Bee-eater (Merops apiaster). Many Israeli bird ringers won't agree that this is a nice bird to catch, since they can be a plague for farmers and then the ringers have to catch them and take them to some other place! To me it's one of the most beautiful birds to have in hand.
Eurasian Bittern (Botaurus stellaris). When we got the report of a heron sitting in a small pool in one of the big hotels near the North Beach we'd never expected it would be a Eurasian Bittern! The bird was not weak at all, and after release it lingered around the IBRCE for quite some time! It's quite a rare bird in Eilat and its surroundings.
Hoopoe (Upupa epops). It would be a crime to leave out the National bird of Israel, the Hoopoe!

Chaff- and Greenfinches

My last post was almost 1,5 months ago, far too long ago! Now I have some time again and I will post some blogs again :)

The past weeks the weather has been very bad, with lots of rain and wind. I've done some ringing the last month in the garden, not much of interest but last monday I had quite a decent morning with Greenfinches and Chaffinches.

Lots of Greenfinches and Chaffinches have been coming to our feeders which is nice. Usually when I put up my net I catch a Greenfinch and then all the Greenfinches know the net and I won't catch them anymore during the session. Due to the dreary weather last monday the net was hardly visible resulting in an increase of Greenfinch catches. This gave me a chance to have a close look at them again. They're certainly not the easiest to age, so it's a nice practice to catch some. Chaffinches usually see the net very well, they fly towards the net and just in front of it they bend off..

I managed to catch:

Blue Tit 4 - 2
Chaffinch 3 -
Greenfinch 5 -
House Sparrow 2 -

Total 14 - 2

I ringed three Chaffinches, 2 adult males and 1 cy female.

Four surprises in the net!

During the weekends - when I'm not in Wageningen - I try to do some ringing in my garden, and once you're doing it it's quite addictive! Today I had quite a few surprises in my net. I ringed four new species for my garden!
 Goldcrest (Regulus regulus), 1cy female
 Coal Tit (Periparus ater), 1cy
 Marsh Tit (Poecile palustris), 1cy based on the retained tertails, pointed tailfeathers and 3-4 old GC's. First time I've seen (and ringed it!) it in my garden
 Collared Dove (Streptopelia decaocto), finally got one!!!

Tammo with the dove.

There was also a good movement of tits, with some 10 being caught. I also retrapped a Dunnock I ringed on 13-10. Few Great Tits were also ringed.

Pretty little things

After some weeks of no ringing I felt like doing some bird ringing again. On Saturday morning I joined Hans, Gerrit and Tammo for some ringing along the IJssel. I arrived a little bit later but I didn't miss anything so far. Blackcaps were around in good numbers with some 40 ringed in the early morning. So were the tits. Groups of Coal tits mixed with Blue and Great Tits came by, of which we were able to catch some. About 30 Coal Tits came by, but only two responded well enough to the tape to end up in the nets. They don't seem to respond that well to the tape then they usually do.. Anyway, another pretty surprise was a sweet Firecrest. It had been a while that I'd handled one (not if you take all the Golden-crowned Kinglets into account that I ringed last year). We ended the morning with a decent total of ~85 birds.
