Saturday and Sunday 22nd and 23rd June

Kestrel (c) Bark

The moor is looking even more fresh and lush than it did last week, and last week it had looked wonderful. It was warm and humid and the  standing water in the ditches and the scrapes has been topped up again.
Grasses are tall and setting seed across the main fields, brambles are starting to flower, and the hedges are spangled through with wild roses that range in colour from pure white through to deepest pink. At the reedbed the fresh new phragmites has finally made its way through and over the top of last year’s dry reeds.

Young Blackcap and Robin (C) Bark
There was still birdsong to be heard as I arrived in the carpark field. Chiffchaff, Willow Warbler and Blackcap were going strong and as I walked along the bridleway Sedge and Reed Warblers were advertising their presence. There were several Cuckoos calling and we watched one, presumably a female, sitting on top of one of the reedbed willows searching for a careless Reed Warbler to parasitise. Several times Cuckoos perched up in the oak trees behind the first screen calling intermittently.

A pair of Ravens cronked their way directly over my head on Sunday morning. Their flight was not direct and purposeful, they tumbled and chased each other in what looked to be a mixture of display and sheer exuberance.  

There were a couple of both Lapwing and Redshank chicks around the scrape on Greenaway’s. 
Lapwing chick and Snipe (c) Bark
As the summer progresses, we should be seeing some muddy margins from the first screen, which should encourage passage waders. Last week a pair of Black-tailed Godwits called in briefly.

At the second screen there are still several Common Tern chicks showing on the tern raft. The adult birds are coming in and out with fish and although somewhat diminished they will still fledge some juveniles. There was one on Sunday that has almost learned to fly although it could only manage to flutter up vertically a couple of feet before parachuting back down.

There is one Hobby that is taking up a regular perch on a fence in the middle of Greenaway’s. By mid-morning this weekend it was up and about chasing down dragonflies, skimming low over the ditches almost disappearing at times below the height of the grasses.
Long Tailed Tit (c) Bark

In the hedgerows and in the carpark field there are now frequent mixed parties of young birds feeding together, taking advantage of the mutual security that many eyes offer. There are still some family parties to be seen, where the adults are feeding newly fledged chicks out in the bushes.

Marbled White Small Tortoiseshell and Painted Lady (c) Bark

The sun has brought on butterflies in good numbers. There were Small Tortoiseshells and a couple of Painted Ladies nectaring on the flowering privet along the bridleway. Along the Roman Road there were Speckled Woods and a few Large Skippers, in Long Meadow there were pristine newly emerged Marbled Whites. There were a number of orangey day-flying moths near the first screen that frustratingly failed to sit out anywhere that would give a clear view, I managed just one useable picture, they may be some kind of Carpet moth…… any answers?

6th-16th June

Six Sedgies (c) Bark

After a few very dry months the rains have certainly come at last. The pools on Greenaways have refilled and the Ashgrave scrapes are much wetter. The grasses have shot up and when the sun has occasionally appeared between the showers the moor is verdant and lush. The refreshed foliage is full of insects and the birds with chicks to feed are busy foraging and provisioning their broods. 
Common Tern (c) Bark
The rain has not benefited everything however, the Tern colony, which was doing so very well ten days ago, is much reduced. There are now just six birds still sitting and only three chicks can be seen on the raft. They are at very different stages of development and so must come from different broods. The heavy rainstorms and chill winds will have taken their toll on the downy chicks.
Tern Raft Before the rain (c) Bark
There are young birds everywhere along the hedges and in the bushes. Blue and Great Tits are already coming together into mixed flocks and they are working their ways through the foliage picking up all kinds of invertebrate food.

Blue and Great Tits and a Young Robin (c) Bark
We were lucky enough to be on hand at the first screen just as a clutch of six Sedge Warblers left the nest and huddled together at the top of a hawthorn. The parent birds fed them a couple of times and then coaxed them up into the larger hedge and the oak trees behind where they spread out and didn’t present such an easy target.
Sedge Family (c) Derek Lane
There were another family group being fed outside of the nest in the reeds by the bridge near the hide. I also saw young Blackcaps, Wrens and Robins on Sunday.

Blackcap (c) Bark and Wren (c) Paul Wyeth
There are Tufted Ducks, Pochard and Shovellers all with ducklings of different stages of development on both the main lagoons.
Tufty family (c) Bark
On and over the reedbeds there is lots of activity by the Marsh Harriers. As yet however, we have not observed female Bitterns making their regular and predictable feeding flights. There have just been occasional more random sightings.

There are a number of Warblers setting territories up for second broods. There is a particularly loud and persistent male Common Whitethroat advertising his presence by the kissing gate with almost continuous calling and aerial displays. Sedge Warblers are still bickering with neighbours and the Grasshopper Warbler has started reeling again in the carpark field.

Common Whitethroat (c) Bark

Cuckoos are still chasing and calling, and the females are still looking for opportunities to drop their eggs into Reed Warbler nests. They will not linger long however once mid-summer day has passed.
Cuckoo (c) Bark
There are Hobbies on and around the larger fields and one was showing particularly well on Sunday flying out from a fence post to seize large dragonflies which it returned to its perch to dismember and eat.
Hobby and prey (c) Bark
Invertebrate life is burgeoning. As it gets warmer more and more Dragonflies and Butterflies will be on the wing. Just over ten days ago before the rains set in, I spotted my first Meadow Brown of the year and there were four or five Small Tortoiseshells along the bridle way in the last weekend. There are strange and interesting bugs to be found if one looks carefully enough.
Golden -bloomed Grey longhorn Beetle (c) Heather Banyard
We have been sent pictures of a Golden-bloomed Grey Longhorn Beetle and a Rhinoceros beetle. There should be black Hairstreak Butterflies on the wing along the Roman Road and it will be fascinating to see if we record Purple Emperor again this year.

Paul Greenaway, Otmoor Stalwart and Friend

Anyone who visited Otmoor more than a few times since the start of the Millennium would probably recognise Paul Greenaway who sadly, died last week. He had borne his illness just as he lived his life with quiet fortitude, calmness and humour.
I first met Paul over twenty years ago on Otmoor and our friendship grew around our shared passion for birds, nature and the unique character of the place. Paul was an amateur naturalist in the classic Victorian tradition. He was curious about all aspects of wildlife and would avidly research anything that he came across. He became our “go to” expert on flowers and plants and would photograph and then identify anything that he could not immediately identify. He often contributed images of insects, plants and mammals to the Oxon Wildlife blog and of course posted his bird sightings on the Oxon Birding Blog under the name “Stoneshank”.
He gave a huge amount of time and effort to winter and summer bird feeding programmes. He was conscientious, and he worried about the welfare of the birds if there was harsh weather. His regular and detailed observations were a huge help to the reserve management in documenting and tracking the breeding successes of our scarcer birds.
What we will miss more than anything however is his quiet, helpful and friendly personality. Paul was always happy to talk to people and share his knowledge and experience, as is demonstrated by the number of warm comments that have been made on the Oxon Bird log and on the Otmoor Facebook page.
Over the years I have spent very many hours in Paul’s company walking, talking and watching. It seems impossible to me that we will no longer see him, coming along the bridleway with his scope over his shoulder, walking with his very distinctive rolling gait that meant we could tell it was him from a great distance. It is sad that we  will not be able to joke with him about his winter and summer plumage ( a beard in the winter and clean shaven in the spring and summer). Paul was a true gentleman and an enthusiast. A birding friend once said of Paul that he was “a plumber with the soul of a poet”, I couldn’t disagree with her. The moor will not seem quite the same without him and we Otmoor regulars will miss him massively.

There will be a simple ceremony at the Oxford Crematorium at 2.30 on Monday 24th June to which all are welcome.

Saturday and Sunday 1st and 2nd June

Swan and Cygnets (c) Paul Wyeth

A very warm weekend with a fairly strong breeze and  a little rain by late on Sunday. The moor has quietened down over the last couple of weeks as birds seek to feed hungry broods. There is not the same desperate drive to attract a mate or defend a territory. Despite that we had heard eight of our nine resident warbler species by the time we had got to the path to the first screen.

Whitethroat ,Garden Warbler and Blackcap (c) JR
Grasshopper Warbler eluded us , but that may well have been our increasing deafness rather than the birds not calling, they have to be very close now for me to pick up their reeling. We noticed several more singing Garden warblers this week than last which may well reflect the fact that they were the last migrant Warbler to arrive.

Great Crested grebe and chick (c) Noah Gins
At the first screen the pair of Great crested Grebes are carrying two stripy chicks around on their backs. They were reported to have three chicks on Friday but by Saturday and Sunday there were just two. Last year they failed to fledge any youngsters at all, such is the attrition rate in and around the reedbed.

On Saturday morning a Spotted Flycatcher was seen in the oak trees along the bridleway. It was hunting from the dead branches, sadly we were unable to relocate it later but there are places on and around the moor where we will look for it in the coming weeks. I have also heard belatedly of a passage Osprey earlier in May and so the Otmoor Yearlist moves on by two more species, to one hundred and thirty-five.

Common Tern (c) Bark

The Common Terns on the Tern rafts have not wasted any time in getting going. There are already three chicks on the raft and when the staff went out to the raft, to replace the battery for the electric anti predator fence , they found there are fourteen nests. We watched a parent bird failing to get a fish that  was just too big for it, down a very small chick. The parent bird kept flying out with the fish and dipping it in the water, perhaps to try to lubricate it. Eventually the fish was fed to what must have been the birds’ mate.  
Newly fledged Black Headed Gull (c) Bark
A visitor pointed out a cream coloured bird to us on Sunday morning , standing on the edge of one of the scrapes. When we looked closely, we could see it was a very young newly fledged Black Headed Gull, clearly one of the first from the colony that has  taken up residence on big Otmoor.
Plum pockets (c) Bark
Some of the Blackthorn bushes have grown large distorted hollow sloes. We looked up what they might be, and they are described as “plum pockets”, similar to a gall and are caused by a parasitic wasp, they have certainly grown much faster than the sloes and I can’t recall ever seeing them before in such numbers.

Hairy Dragonfly, Broad bodied Chaser and Four spot chaser (c) Bark

The warm weather has brought on the emergence of adult dragonflies and more butterflies. There are now pristine Four-spotted Chasers, Broad bodied Chasers and Hairy Dragonflies, to be seen in the reeds and along the hedgerows. In addition to the various Damselflies in the vegetation beside the reedbed we are now noticing a few Banded Demoiselles.
Female Banded Demoiselle ? (c) Bark

Last week I put up a  picture of a strange insect that I had spotted in the corner of a photograph of a Dandelion clock. It has been identified as a longhorn micro moth called Nemophora degeerella (thanks to Carolyn Tovell )

This weeks puzzle is a very beautiful iridescent beetle seen eating pollen in a Buttercup flower. Its rear legs look as if it has been on a body building course or like a bumble bee that has collected lots of pollen.

Mystery Beetle (c) Bark
The Dog roses are now out in force splattering the hedgerows with every shade from white through to deep pink, pannicles of elder flowers are scenting the air with their distinctive smell and along the path to the first screen is a Privet in full flower giving off its strong perfume.
