February round-up and spring on its way.

The colder weather of early in the month has given way to much milder conditions with fewer frosts and the frozen water bodies have thawed. As often happens at this time of year the Starling roost has collapsed, and they have moved elsewhere.

Thousands of Golden Plover (c) Bark

Despite the absence of all the Starlings, Otmoor is still hosting well over fifteen thousand birds. This number is made up by nearly five thousand Lapwings and five and a half thousand Golden Plover. Teal and Wigeon together number over four thousand and the other duck species make almost another thousand.  

Lapwings (c) Bark

(these figures come from the WEBS count taken this Monday 20^th February, by the RSPB staff.) The count does not include the fluctuating flocks of feral Geese that are currently scattered across the moor and surrounding farmland.

Bald numbers however do not do justice to the sheer spectacle of seeing so many birds flushing in response to hunting raptors or to other threats, real or imagined. It is sometimes possible to track the progress of a raptor hunting across the fields as flock after flock takes off in panic at its passage. At times the sky seems to be full of birds in every direction one looks.

The Lapwings and Golden Plover show different behaviours in their response to threats, with the Goldies flying tighter with more twists and turns, they fly higher and form loose skeins as they start to settle again. The Lapwings however spread out much more and their flocks are looser. On days when there is bright light in the south and lowering indigo clouds in the north the birds twinkle and sparkle as they turn in the sky flashing black and white.

Last Saturday we were helping a group of the Otmoor Volunteers with some winter id tips followed by a walk out to the reedbed to put the talk into practice. I had produced a Power Point presentation to illustrate some aspects of the id issues raised. My penultimate slide showed the difference between Eurasian Teal and Green-winged Teal and the difference between Eurasian Wigeon and American Wigeon. It mentioned that there had been an American wigeon at Port Meadow briefly and so it would be worth looking carefully at any Wigeon on the moor. I also explained that an American Wigeon would be a first record for Otmoor. We duly carried out our walk and spent some time scoping through the massive flocks of birds out on the Flood Field. We found the Black Swan that was also mentioned in the presentation, which I had not realised was there, but we failed to spot the American Wigeon.

The bird was found by Fergus Mosey, the RSPB warden, whilst doing the WEBS count last Monday morning. It was seen occasionally during the day although the light was difficult and again on the next day. It has been seen intermittently throughout the past week sometimes on Big Otmoor and more regularly on The Flood.

There are currently five Cranes on the moor a pair and last years successful pair with their offspring still in tow. They are very vocal at the moment and often announce the fact that they about to fly by bugling loudly. It may be that the pair with the juvenile may try to push it away now, if they are to breed again this year.

There seems to be two clear territories with some common ground in between a lot of the bugling is about establishing boundaries. It will be interesting to watch the evolving soap opera as it develops during the spring, and to see if the cast is supplemented by any further pairs or singletons.

This month just as we expected and right on cue Redshank and Curlew have returned. There are only a few Redshank at present but there were thirteen Curlew recorded on Monday. An Oystercatcher has been seen and several Dunlin. The water levels are looking good for passage waders and the centre of Big Otmoor is looking as though it will soon become the Otmoor “hotspot”. It is very well worth checking it out from now onwards for early returning Garganey.

Lots of mammals, a very confiding Muntjac, a quicksilver Weasel and a mad Hare (c) Bark

It has been an exciting week and the Otmoor list now stands at ninety seven species, the only downside of the latest find on the Reserve is that it has made my “Birds of Otmoor” booklet outdated once again !

Birds on a Branch......and January Update.

The Branch

There is a row of mature oak trees that forms the border between the path beside the reedbed and Big Otmoor. One of these old trees, the nearest to the first screen, has a twisted, scarred and naked branch that reaches above the canopy.

   

Used by everything from Kites to Blue Tits

This branch has a deeply etched surface and a jagged shape not unlike a negative image of a bolt of lightning.

Its height and position mean it is a superb lookout point, a song-post from which to broadcast calls or perhaps just a safe staging post along the hedge.

Cuckoos use it to broadcast their calls.

Over the years I and many other birders have seen a variety of different birds taking advantage of this perch, from Red Kites at one extreme to Blue Tits at the other and indeed many species in between.

Both common Woodpeckers use it.

We have photographed them when we could although some of the more unusual birds were missed, like a Merlin that flew just as I lifted the camera, or the Hoopoe seen in June 2008.

 Kestrels hunt from it.

Starlings use it when they come out of the roost.

  

 Passage Wheatears and newly arrived Swallows perch there.

 

   

It really is an Otmoor icon!

I have not added individual credits to these images for fear of getting accreditations wrong, suffice to say that some of the images are mine, some JR's, some Mark Chivers and one at least Trish Millers. If anyone has images of any other suitable birds I would love to add them to this blog entry. Bark.

January Roundup. .

Mallard over a frozen reedbed (c)Bark  

 

A period of thaw and freeze with the latest freeze just having ended after a couple of hard frosty weeks. Water bodies across the moor were rock solid  with just the ring ditch still flowing. There is now a lot of water across the reserve, with the flood field finally living up to its 

   

 Lapwings and Goldies

Before the latest  freeze bird numbers had risen to an estimated ten thousand birds across the whole moor. There were at least three thousand Golden Plover and a similar number of Lapwings, the remaining numbers were made up of wildfowl. Five or six hundred feral Geese are grazing across Ashgrave and Big Otmoor and there several thousand ducks with over a thousand Teal and a slightly smaller number of Wigeon. Shoveller numbers finally went up, having been uncharacteristically low during the late autumn. In addition to the birds I’ve just mentioned there were at least fifty thousand Starlings arriving each night to roost in the reedbed.

During the latest ten day freeze the majority of waders and wildfowl left the moor for the rivers or areas of deeper open water. They now appear to have returned and last weekend we estimated that there were over seventy Pintail amongst the other duck species.

   

Luke and Friends. 

Another returnee is “our” leuchistic drake Pochard “Luke”. We have been reporting on him and watching him since 2015, he was out on the northern lagoon with three other drake Pochards. Golden Plover and Lapwing numbers have not got back to where they were yet but are well on their way and February is usually when we see their numbers peak. The first Ruff of the year were also reported last weekend and it will not be long now before we see and hear returning Curlew.

We heard a couple of Cetti’s calling on Sunday along the bridleway and by the path to the second screen a reassuring thing to hear after a string of days when the temperature failed to get above zero. The Starling roost appears to have collapsed now as is normal after a spell of very cold weather. When the water across the reedbed freezes roosting birds are vulnerable to predation from mammalian predators coming across the ice and taking them from below.

We are still seeing similar numbers of raptors across the moor including the Ring-tailed Harrier, Peregrines and Merlin. The winter finch feeding programme is attracting large numbers of Linnets, Reed Buntings and Chaffinches, along with a scattering of other seed eaters. They in turn are attracting Sparrowhawks in search of an easy meal.

Waiting for lunch

The reed cut that has been carried out in the southern reedbed does not seem to have pushed the otters away although they were not so visible or  obvious during the freeze. They have attracted large numbers of people to see them and almost become stars on social media!
