Eagles and Owls in Netherlands

Caspian Plover, Brown Shrike, Hawk Owl, Snowy Owl. All mouthwatering prospects and at one point all available in the Netherlands recently. It was this tempting combination that got me thinking about making another winter trip to this superb birding destination. I hadn't been for some years but the combination of a large wintering population of quality birds, an active local birding scene and outstanding dissemination of news means it is always a good option. So when my sister, who works for Stena, said she had some free tickets for the Harwich - Hook of Holland crossing going begging I jumped at the chance.

I soon had a willing team of old friends together and a weekend selected for the twitch. In the meantime the Caspian Plover got eaten by a Merlin and the Snowy Owls were reduced to a single bird on Vlieland (an island impractical to get to on a weekend trip). That still left the Hawk Owl and Brown Shrike plus lesser goodies so the trip was still on.

Departure was after work on Friday and a 2 hour drive to Harwich International Port. We were soon checked in, boarded and settled in the Metropolitan restaurant on the Stena Hollandica for a slap up three course meal (included in the free tickets!).

After a comfortable night in the cabins and an included all-you-can-eat breakfast we were on the road heading north towards Zwolle and the Hawk Owl. On the way we stopped by the motorway at Nunspeet and had terrific, if damp, views of Short-toed Treecreepers and Crested Tits.

Generally reliable the owl had not been showing the previous day but had gone missing for a single day before during its long stay so we were fairly confident of relocating it. However after a couple of hours searching in the pouring rain it was clear all was not going to plan so rather than wreck the whole day we drove a short way towards the Ijsselmeer near Kampen and ended up watching Goosanders, many Smew, other wildfowl, waders and a magnificent pair of White-tailed Eagles all on the Vossemeer.

The eagles were amazing entertainment, at first flying into a huge dead tree and breaking off a large branch with their combined weight then the male flying off and catching a large eel and eating on the mud opposite attended by daring Carrion Crows who were eventually rewarded with the left overs.

Nearby one of the many Great White Egrets scattered across the Netherlands showed well enough for a record shot.

Very happy with the haul of birds here we returned for another go at the Hawk Owl in drier and brighter conditions but it was not to be. So in the failing light we headed south to our hotel in the little town of Zeddam tucked up against the German border close to a bit of rare Dutch high ground. We spent a very pleasant evening in Zeddam finding a cracking little Italian restaurant run by a Sardinian family who provided some excellent food and drink and a very warm welcome. It was fun being Brits in an Italian restaurant on the Dutch/German border hearing people saying 'bon appetite'! An international occasion.

On Sunday we were out at dawn to find a much drier, brighter, but hellishly windy day. Not the best conditions for locating a shrike and sure enough after a couple of hours we were facing the prospect of missing out on both main target birds. But birders are made of sterner stuff and we were consoled for a while by the sight of a Goshawk, which few see often in the UK, and again decided to take a break from the search, this time to do some birding in the nearby Bergherbos woodland. This holds Black Woodpecker which is a good bird by any standards. Unfortunately the wood is very popular with dog walkers, joggers and mountain bikers (being on a slight hill - a novelty for the Dutch) on a Sunday and the wind was not helping, so a distant call is all we encountered of the big woodie. Willow and Marsh Tits, more Short-toed Treecreeper action, Nuthatch and a few Siskins and a Great Spotted Woodpecker would have to do, although a small party of Common Crossbills were a nice addition just before we left.

Soon it was back to the search and still there was no sign of the shrike. So I made a decision to return to the hotel and use the wifi to check the news to see if the owl had been seen that morning. We could easily give up on the shrike and return to Zwolle if it had. It hadn't, but the shrike had. There had been a sighting shortly after we'd left for the wood. Rats! Nothing for it, we would have to go back for a third time and try again. There had been other birders there looking on and off all day but this time we met up with one of the patch workers responsible for finding and reporting the bird. Despite some pretty ropey optics he managed to refind the bird within about 30 minutes! Were we just rubbish or was it a case of the weather improving and knowing exactly where to look? In any case we were very grateful and all enjoyed good if rather distant views of a Brown Shrike that should have been wintering in South Asia, where I might see more of them in a few weeks time.

Our ferry home wasn't until late that evening so we had time to play with and decided geese were the best target. We'd already seen plenty of Greylag, Canada, Egyptian, Greater White-fronted, Pink-footed and Barnacle Geese everywhere and a couple of suspected Bean Geese had passed over us while we searched for the shrike but there were two rarer geese that were also tempting.

Our first site just south of Utrecht was unsuccessful apart from yielding our only Pheasant of the trip :). But we were luckier with the second. With not much more than an hour of useful daylight left we arrived at the goose-mecca of Strijen. This small area of polders west of Dordrecht can be a bit daunting at first. Confronted by thousands of Barnacle and White-fronted Geese it can be hard to see how you are going to pick out the tiny number of rarer species among them. While searching we got good views of another Goshawk, hunting the open wet grasslands in habitat UK birders would not expect to find them, and plenty of Brown Hares.

Brown Hares Lepus europaeus

Then we struck lucky when I picked up a group of 3 small grey geese on the edge of a Barnacle flock. These were soon confirmed as Lesser White-fronted Geese before they flew a short distance to join a fourth bird. A lifer for some of the crew it was good to see them, especially as Chris and I had just missed them on our trip to Northern Greece a couple of years ago.

Finally while scanning the last Barnacle flock Chris located a Red-breasted Goose emerging from one corner of the flock. You could see just how hard it can be to pick these out as the tiny goose was there one minute then vanished among the flock the next. Another lifer in the bag for some. A second Goshawk, a male giving us the best views yet of a species that I've only seen once or twice in the UK, was the last notable bird sighting before we headed back to the ferry port on the last fumes of the hideously expensive Dutch unleaded.

Our timing was perfect and we rolled straight onto the Stena Brittanica and were soon celebrating in the Metropolitan restaurant before retiring to our cabins for another comfortable crossing of the North Sea and the early morning drive back to work in Peterborough on Monday morning.

My thanks go to the rest of the team, Mike Weedon, Chris and Lloyd Park for making this such an enjoyable weekend and especially to my sister Jane for the opportunity to travel in style on the Stena crossings.

Willow Tit at Deeping Lakes

This is a screen grab from the video below and shows many of the salient feature that separate this species from the very similar Marsh Tit: the wrap-around white cheeks, dull black crown and lack of pale base to the cutting edges of the mandibles as well as the very clear pale secondary panel.

More distinctive though is the call which is how I picked up the bird in the first place.

Burghley House

OK, so the deer are captive but also rather cool. The Goosander however is one of 6 wild birds on the lake: 4 males like this one and a couple of females.

Acleris hastiana and a garden first

It's not only Winter Moths in the winter. This attractive little micro came to a window on Boxing Day. Only the second record for the garden.

Acleris hastiana

In other news my local recorder has finished microscopic identification of the few moths taken throughout the year. There are a few oddities to sort out but this one at least was a garden first.

A Sitta

Over the past few days there have been a few birds that are a little out of the ordinary. Not rare, just not that frequent. Last Sunday a male Bullfinch flew high south along the Nene and a Chiffchaff was in the garden, on Tuesday a Tree Sparrow flew over the house calling (and it took me a few minutes to register that call I hear so rarely these days) and this morning the first Fieldfares and Redpoll of the autumn flew over.

So I nipped up Greenhill this morning to see what was about and came across a couple of Nuthatches slightly out of place around the horse paddocks. Otherwise just some Woodpigeons on the move and a few more winter thrushes.

Buff-breasted Sandpiper

We only went to Frampton Marsh RSPB reserve as somewhere for a walk but it was nice to see plenty of birds after the relative dearth in the Peterborough area recently. Apart from the Brent Geese, Little Egrets, Ruff and Black-tailed Godwits there we quickly found Curlew Sandpiper, Little Stint, Spotted Redshank and Knot but it was extremely windy so anything other than wildfowl and waders keeping its head down.

Then heading along the road to the sea wall a small party of Ruff flew from the meadows and onto the freshmarsh nearvy. There was a small wader with them that sparked my interest so I scoped the flock on the deck and picked up this Buff-breasted Sandpiper. Not all that easy to get good views at it was being chased around the vegetation on an island until it had had enough and flew off on its own. Frustratingly there was not another birder in sight and no way of getting a message to the visitor centre so I reported the news to Birdguides and caught Karen up to continue the circuit.

An hour later I was meeting birders arriving to see the bird and of course there was no sign so it was relief when I got home and found that it had been relocated, back on the grassland, a couple of hours after my first sighting. Among those relocating it were the current and former county recorders, John Badley and Steve Keightley and through them I have this photo by Steve.

Corizus hyoscyami

Bug time again. Several of these disturbed from hedging while pruning this morning. A formerly coastal species that has spread inland in recent years.

Nut Weevil

Another non-lep at the moth trap last night. Curculio weevils are a bit tricky but with the aid of a bit of magnification you can see the shape of the segments on the antennae confirming the ID. The inset picture below comes from here and shows the Acorn Weevil (C. glandium) on the left and this species on the right.

West Penwith Wildlife

Our annual pilgrimage to the far west of Cornwall yielded a excellent haul of wildlife images. This post very nearly didn't happen due to the mysterious case of the disappearing SD card. The card then miraculously and happily appeared at the bottom of a very unlikely rucksack on our return. Phew!

The wildlife was dominated by a strong passage of Manx Shearwaters over the sea on several days but the only Balearic Shearwater to show, which landed very close to the house and well within filming range, unfortunately left before I could fire up the equipment. Otherwise the highlights were an amazing Ocean Sunfish, several Basking Sharks, a single Harbour Porpoise and a couple of playful Grey Seals that approached the canoe near the Minack Theatre. I'm sure one was purposely surfacing just behind the boat and expelling air suddenly to try and make us jump.

Ocean Sunfish Mola mola



You get an idea of scale as this medium sized Basking Shark passes the Pilot Gig 'Brisons' just off Sennen Cove.

Basking Shark Cetorhinus maximus


This Slow Worm appeared on the path in front of us during a long walk in the Bosigran Farm area between Zennor and Pendeen.

Slow Worm Anguis fragilis



One of the more intriguing beasts was this tiny, early instar nymph of a scarce bug spotted by Alex while climbing in the idilic, secluded cove of Green Bay near Porthcurno. It really is very small indeed but rather distinctive with the spiky and hairy legs and antennae and striking colouring. It is a specialists of soft cliffs and dunes.

Boat Bug Enoplops scapha, 2nd instar nymph

The Emperor Moth is striking enough as an adult, but as a caterpillar it is a mean, green, eating machine.

Emperor Moth Saturnia pavonia, larva

OK, some more insects. No pics of the Red Admirals, Clouded Yellows and Painted Ladies that were around the coasts (and over the sea at times) though I'm afraid.

Common Darter Sympetrum striolatum

Field Grasshopper Chorthippus brunneus

Oh yes, and birds. Sennen Cove has had increasing numbers of Mediterranean Gulls every time I return and this year there were 30 or so. Here are a few in different plumage states and a Kittiwake, a species that joined them in varying numbers on the shoreline.

Athalia Sawfly

This genus of sawflies is difficult to identify to species but I've read that the arrangement of teeth on the ovipositor of the female can be used and, happily this is a female. The USB microscope has revealed some detail so posting this on the offchance that someone has the necessary literature and can help.

Honeysuckle Moth

Another addition to the garden moth list. Quite a common moth so surprising it hasn't turned up before. A rather distinctive little fella with the characteristic ypsolopha 'headstand' resting posture but a more individual upturned and divided wingtip.

More microscopic fun

A couple more insects identified with the help of the little USB microscope. The first is a possibly scarce leafhopper dependent on elm. Unfortunately deceased, but the closeup shows the three spurs on the tip of the hind femur typical of the genus. The only other species has no all-green form.

The fearsome large red ichneumon is a common species, one of two with these yellowish markings around the head and thorax. The other differs in the distance of the ocelli (the black 'eyes' in the middle of the head) from the occipital carina (the faint brown suture line at the back of the head) and the shape of the abdomen.
