There has been rain in the previous week and again overnight
at the weekend. On both days, there was a moist heaviness in the air and first
thing the vegetation was bowed down with drops of water. The foliage was
refreshed after the prolonged dry spell and there were insects everywhere.

Young birds and passage waders are the key things to look
for at the moment and the breeding successes of what were once scarce
Oxfordshire birds is a tribute to the way the reserve has developed over the
past twenty years.

It is now clear that there are two separate broods of Marsh
Harriers around the reedbed. Two birds have been perching up in the bushes on
the north-eastern side bordering the flood Field. These two are being
provisioned by a female that is moulting some primaries and is looking very
scruffy. The other two youngsters can be seen perching up in the hedge along
the back of Greenaways. All of these youngsters sit scanning the sky for the
returning adults and await a food-pass from a parent bird.

The number of Common Terns at the Tern raft has gone down as
chicks have fledged and have moved off with the adults. There are still a few
that are being fed on the raft and making occasional inexpert sallies over the
water. The Black Headed Gull pair have raised one youngster to flying and are
so vociferous in their defence of it that they chase ducks away from it if it
gets too close to them. They take a very aggressive approach to the Little
Egrets that just want to loaf about on the dead branches on the emerging muddy
margin. They also challenge any raptors that stray too close.

There are now an indeterminate number of newly fledged
Bitterns in the reedbed. Early last week two were seen landing clumsily in the
reeds fringing the northern lagoon and possibly another was photographed from
the high seat, after an uncomfortable three-hour session, by T.S. This bird was
confirmed by Ian Lewington as being a pristine juvenile. As the season
progresses we will expect to see them moving about within the reedbed and
beyond in the channels and ring ditches across the reserve. If previous years
are anything to go by the best chance of seeing them out in the open will be in
the reed fringes of the northern lagoon.
There were waders to be seen this weekend.

On Sunday we saw two Hobbies perched up on the high seat. We
could scope them and one was clearly a juvenile, they were joined by another
adult before flying off and starting to hunt over Big Otmoor. The transitional
plumage male Hen Harrier is still being seen regularly hunting across
Greenaways and the hedge along its northern edge. I saw it myself twice on
Sunday, on first glance it looks as if there is a medium sized gull quartering
the field but its flight pattern and agility are totally un-gull like.
Quail was heard again calling on Saturday morning from Big
Otmoor, approximately half way along the bridleway towards Noke. Redstarts are
now regular in Long Meadow and a young Spotted Flycatcher was seen on the wires
in the Car Park Field and a further two birds were in Long meadow beyond the
old brick stop-butt.

For a digest of what might be found on the moor in late
summer/early autumn there is an article in the latest edition of Birdwatch
magazine that says where to go and what one might see. Enjoy it.
