17th April – Mordon Bog   Leave a comment

I had been looking forwards today. The forecast gave southerly winds and heavy rain clearing by mid-morning. This should have been ideal for seawatching from Portland Bill, but a quick call to the Observatory before I left indicated that the rain had already cleared and the winds were now westerly and hadn’t produced very much, so I decided to stay local. By the end of the day they had amassed a good number of Bonxies (Great Skuas) but not, considering the time of year, a lot else.

I ended up at the Sherford Bridge / Mordon Bog area, but was unable to find the Hobbys, Cuckoos and Tree Pipits that had been seen by others in recent days. All was not lost as I saw a couple of Crossbills, a Raven, heard a Woodlark and had a few Swallow pass by. The woodland areas allowed me to photograph a Treecreeper, Goldcrest and Mistle Thrush.

Decoy Pond lies in the middle of heathland and usually supports a couple of pairs of Tufted Duck and Little Grebes. It is not to be confused with the nearby but much larger, Mordon Park Lake, which is surrounded by dense deciduous woodland.

The remnants of Decoy Cottage. When I first started birding in this area 33 years ago the cottage was intact, yet abandoned. It is said that the ghost of the last owner still walks the forest!

With grey skies and intermittent rain, most birds were silent, except of course several Mistle Thrushes which were living up to their old name of 'Storm Cock'.

This Treecreeper seemed oblivious to my presence.

It remained cold and windy all day. The temperatures are at least 10 C lower than they were last month and migration, which seemed so promising in late March, has ground to a halt. With reports of bad weather to the south and even snow in Morocco, this is perhaps not surprising. A transient desert lake on the fringes of the Moroccan Sahara was bone dry in mid-March but measured 10km by 3km and had diving Little Grebes on it two weeks ago!

16th April – Ower, Middlebere and Lytchett   Leave a comment

On the 16th I opted for Ower on the south side of Poole Harbour. Things had changed a lot since my last visit in March. Treecreepers, Nuthatches, Marsh Tits and Siskins, although all still present, were far less conspicuous, whilst the air was filled with the sound of Chiffchaffs, Willow Warblers and Blackcaps. Of course there was no sign of my main target, whose name I shall now refrain from uttering until I actually see one!

The banks of the stream are carpeted in Primroses.

The Wytch area of Poole Harbour, the site of Europe's largest on-shore oil field.

 

 

I then headed for Middlebere on the way back. An Osprey had been seen the previous day. Ospreys predilection for this area has led to the RSPB erecting dummy nests in the hope that a migrant pair will stop and join the party. This hasn’t happened yet, but it’s become a reliable site for them in autumn and sometimes in spring as well.

Very little was showing from the hide but along the access lane  whilst watching a singing Chiffchaff,  a Dartford warbler appeared right next to me allowing a great photo opportunity.

 

Singing Chiffchaff. I thought I'd 'go large' on these three images.

 

A very obliging Dartford Warbler.

 

Garden moluscicides have led to big losses in the Song Thrush population, but this year they seem to be everywhere. lets hope a recovery is underway.

 

Finally I called in at Lytchett Bay, where I finally got a glimpse of a Reed Warbler but not much else.

 

Last year the farmer left a wide 'conservation margin' around this field which proved excellent for buntings and finches in the autumn. This year its been ploughed right up to the hedge.

14th – 15th April – Durlston and home.   Leave a comment

Saturday morning saw three of us ringing at Durlston. Unlike our very succesful visit on Thursday there were few migrants about and only 15 birds were ringed, mainly Chiffchaffs, Willows and Blackcaps, but three Bullfinches was noteworthy. It was particularly cold and it seemed to take until mid afternoon to get warm again.

Although I have seen a few female Blackcaps in woodland, most migrants I see at this time of year are males.

 

As well as differences in leg, flank and overall body colour, wing formula and wing length, Chiffchaffs have a more domed head, a more obvious eye ring and a less prominent supercillium compared......

.... to a Willow Warbler.

 

Once slaughtered in their thousands due to the damage they inflict on the buds of fruiting trees, Bullfinches were also kept as cage birds and whistled at until they learned a tune (as mentioned in 'Tess of the d'Urbervilles). Fortunately neither activity is performed today!

The classic method of ageing Dunnocks is on eye colour, muddy brown in first years, mahogany in adults. Unfortunately by the turn of the year this feature become unreliable.

 

We have been looking into the using the black bar on the primary covets as an ageing feature in Dunnocks, well-defined in first years, diffuse in adults. The results so far look promising.

 

On Sunday we settled down to various chores at home. Margaret spent much of the day in the garden, the benefits of which can be seen below. I continued on with my copying of old cassettes on the PC; listening to sixties legends as Janis Joplin, The Rolling Stones and Jeffereson Airplane took me back to my youth. I am also attempting to tidy up and modify the taxonomy on my Wildlife Recorder database and have been running into big problems. More of that when the problems are resolved.

 

This was the garden when Margaret moved in four and half years ago .......

 

..... and this is it today!

11th – 13th April, Portland, Radipole, Durlston and Lytchett Bay.   Leave a comment

On the 11th I returned to Portland. With less wind there were fewer seabirds, I saw a number of Manx Shearwaters from the Observatory patio, along with a few Scoters. There was a good number of birds ringed, mainly Willow Warblers (I usually don’t get involved in the ringing at Portland as many ringers take holidays there specifically to ring and I wouldn’t want to get in their way).

This is the view from the Bird Observatory patio. Most seabirds pass in the tidal race, the area of white water in the mid distance.

The most interesting bird as far as I was concerned was a ‘Greenland’ Wheatear  in the hand. This larger and brighter subspecies of Northern Wheatear breeds in Greenland and eastern Canada but like all other Wheatears it winters in Africa. This bird was trapped along with a nominate Wheatear and it was great to see a side-by-side size comparison in the hand, something I haven’t been able to do before.

The larger and brighter Greenland race of Northern Wheatear, in less than a week it could be in Arctic Canada.

Northern Wheatears have an almost circumpolar distribution; birds have spread into Alaska and western Canada from Asia and eastern Canada from Greenland.  It had long been thought that Northern Wheatears that breed in the New World winter in Africa (as well as the entire Old World population, but proof has only recently been available through GPS tagging and stable isotope analysis. The journey from Alaska is about 15,000 km, that from eastern Canada is about 8,000 km but most of it is over the Atlantic. More details can be found in the most recent edition of Birding World.

On the way home I had just got to Dorchester when I received information that there was a Black-winged Stilt at Radipole, I quickly turned round and headed back.  After receiving a worrying text that it had just flown off, I arrived at North Hide to find it had returned and I was giving good views, if not good photos.  This species is a regular but rare overshoot to the UK in early spring. I have seen nine individuals in the UK (one that stayed for years in Norfolk was seen many times) but this was only the second I have seen in Dorset, the last being in 1985.

The view from the north hide at Radipole. The Stilt spent most of its time behind the bush at the back left of the picture.

Record shot of the Black-winged Stilt. Far better photos exist on the Dorset Bird Club web site.

A heavy shower was brewing and these Mute Swans flew directly towards us with the ominous sky as a back drop.

The following day I did some ringing at Durlston. Four of us had a productive morning, with 72 birds ringed. This is probably our best ever total for a spring session. We are seeing plenty of Willow Warblers moving through but other species are conspicuous in their absence. Hirundines (swallows and martins) have hardly put in an appearance at all. Up to the 12th I had seen less than ten, however there was a small movement today and I even got to see my first House Martin of the year.  We also heard a Cuckoo and a Grasshopper Warbler nearby, but it was surprising that we heard anything at all given the unholy din that emanated from people training their dogs just the other side of the garden wall. When we took the nets down I nearly stepped on an Adder but it slithered off into the undergrowth before I could get a photo.

Peter Williams from Worth Matravers had an even closer encounter with an Adder, whilst gardening this Adder bit him on the hand. This is of course our only poisonous snake and he spent much of the Easter weekend in A&E.

In the evening I paid another visit to Lytchett Bay as the Cattle Egret had been seen again. I think I must have arrived too late as all the Little Egrets had gone to roost, presumably taking the Cattle Egret with them.

Late evening at Lytchett Bay

Much of the 13th was taken up with various tasks but another late afternoon visit proved third time lucky and the Cattle Egret showed well. I also heard my first Reed Warbler of 2012.

Cattle Egrets are becoming much commoner, this is my third bird of 2012.

Another bird that has increased greatly in numbers is the Mediterranean Gull, now breeding in moderate numbers in Poole Harbour, their loud mewing could be heard all the time this evening.

10th April – Portland   Leave a comment

Yesterday we had our first really wet day for ages, what the BBC weathergirl called ‘usable rain’, but today was clear and sunny if quite windy. The wind was blowing from the south-west, so there was the promise of some seabirds at Portland.

First I called in at Barleycrates Lane in the hope of another Ring Ousel but all I found was a Blackcap so I headed for the Bill a bit of seawatching.

The trouble with seawatching is that often that is exactly what happens, you end up watching the sea rather than seabirds.

 

Along with several of the Portland regulars I was able to see my first Manx Shearwaters and Puffins plus a few Sandwich Terns. Later back at the Observatory a couple of Arctic Skuas put on a great show offshore, chasing Kittiwakes and Sandwich Terns over a protracted period.

 

Manx Shearwaters were seen with the Gannets off the Bill Photo from the Internet.

 

This dark phase Arctic Skua gives a pretty good idea of the sort of view I was getting from the Observatory patio. Photo from the Internet.

 

On the way back I called in at Lodmoor where a pair of Bearded Tits and a Marsh Harrier where the best birds, before heading back to Upton and Lytchett bay where a Cattle Egret had been seen earlier. At least a dozen Little Egrets were present but no Cattle, perhaps it had gone off in search of some cows.

7th – 8th April – Durlston and New Forest.   Leave a comment

On Saturday a group of us tried ringing at Durlston. I say tried because it took two hours before the number of birds ringed exceeded the number of ringers present. However, we did have two gems, a control Chiffchaff (ie one that had been previously ringed elsewhere) and a Grasshopper Warbler, one of the very few I have seen in the hand in the spring. It was a cold and breezy morning and we couldn’t help feeling that summer has already been and gone!

Grasshopper Warbler. In most years I only hear their insect like buzz in the spring and have to wait until autumn ringing sessions to actually see one.

 

On Sunday Margaret and I birded a few sites in the New Forest, I was hoping for a few spring migrants like Redstart or perhaps even a Cuckoo, but all we managed was a few Chiffchaffs and Blackcaps and a single Willow Warbler. Of course what I really wanted to see was the bird that is fast becoming my nemesis, Lesser Spotted Woodpecker. I went to three sites where they have been seen, Cadman’s Pool (where I have heard them drumming), Bolderwood and Anderwood. Best birds were a pair of Marsh Tits at Cadman’s Pool plus a Firecrest and a pair of Hawfinches at Bolderwood. Again it was a grey and rather cold day, but there were lots of cyclists on the trails and the Bolderwood car park was full to overflowing.

Although Hampshire is under a drought restriction, i.e. a hosepipe ban, the New Forest streams seem to be at a healthy level.

4th – 6th April – four out of four in Devon.   Leave a comment

On the 4th and 5th I just did a bit of birding at Lytchett Bay. The weather was mainly cool and grey and there were only a few migrants about, a Greenshank was probably the best bird, although a male Redstart was seen on the 5th by Paul Morton.

A cool and grey day at Lytchett.

With a couple of good birds in eastern Devon, Margaret and I headed there on Good Friday. First we drove to Budleigh Salterton as a Purple Heron had been seen near the River Otter for the last couple of days. It was pretty cold but gloriously clear but no amount of searching could reveal the heron so we assumed it had gone.

The River Otter at Budleigh Salterton.

We then drove on to Teignmouth but as we were going to be driving close to Exminster, it seemed sensible to try to see Cirl Buntings on route. I had tried at the same spot in January without success but they may have been wintering elsewhere It took about 20 minutes of searching to find a male, which conveniently briefly sang before it flew.

A male Cirl Bunting photographed in the same area last June.

With at least one year tick under the belt, Little Haldon golf course near Teignmouth was our next destination. We arrived to hear that the Hoopoe had been showing well but now there were many golfers on the course and it had become very flighty. Stopping for the Cirl didn’t seem like such a good idea now. It took a while but then we saw it in a gap in the vegetation on the edge of the course, just time for a couple of photos before it flew.

Time for a quick photo .......

... and then it was off !

A short break for lunch at Teignmouth was hindered by the masses of grockles along the seafront, what this place must be like in August!

The beach at Teignmouth, not too many on the beach but the car parks and esplanades were packed ......

... and the estuary was busy too.

Pied Flycatcher is a scarce but regular migrant in coastal Dorset, but I often miss them in spring when the males are in their breeding finery and end up searching for drab autumn birds. Breeding is confined to the Sessile Oak woods of western Britain and there was one such wood just 12 miles away. As it was still early April and to the best of my knowledge only a single migrant had been seen in Dorset this year, so my expectations were low. However we soon found a singing male by the hide.

A breeding plumaged male Pied Flycatcher is a sight to behold.

Wintering in tropical west Africa and breeding in western UK, this species has benefited from nest box schemes.

Back near the car park there was two pairs of Mandarins and a Wood Duck on a woodland pool. Mandarins were first introduced to the UK in the early 20th century and is slowly spreading from its stronghold around London. Wood Duck occupies the same niche in eastern North America and although it has been released in the UK it not established a self-sustaining population. There has been speculation that wild might birds might reach us from the USA, following records in the Azores and Iceland.

East meets west in deepest Devon. A pair of Mandarin and a drake Wood Duck (at the back) on a woodland pool. With a Wood Duck in Devon and another at Abbotsbury there must be an influx from the States (!)

The amazing 'sails' on a drake Mandarin are modified tertial feathers.

We were just about to leave for home when I discovered that the Purple Heron had been see, It hadn’t gone after all! We quickly returned, as I approached some birders pointed out where it was, only to add  ‘ its just gone into the ditch’. I had missed it by two seconds! After ninety minutes of waiting it appeared on the far side of the wooded ditch for just a few seconds, only myself and another birder saw it and all the rest, including Margaret who were on the other side, dipped.

If the Purple Heron had chosen this ditch to feed then there would have no problem seeing it .......

... but it choose the ditch to the south where it fed out of sight. Photo of the same bird from the Internet.

Two vagrants, a scarce resident and a localised summer visitor plus a couple of introduced ducks, not bad for a day in Devon.

Finally a conversation with a passer-by went something like this:

Q so where does this heron come from?

A probably it was flying from tropical Africa to Spain and it overshot and landed here.

Q So it like a normal heron, I mean is it smaller?

A no it’s not really smaller but it is a lot slenderer.

Q Is that because its flown such a long way?
