Singing Dunnock (c) Bark
An overseas
trip has rather blunted my intention to post bi-weekly this year. Change is
happening rapidly on the moor as we move into spring. The weather has been wet
but generally mild and frequently sunny.

Water bodies across the moor are now very much at optimal levels and the
lagoons in front of the screens are looking very full. This water will be drawn
down onto Greenaways and Big Otmoor as we move into summer, and it will help to
keep the main breeding areas for our waders wet for longer.
Redshank on Ashgrave (c) Tom N-L
The first Coltsfoot is starting to flower along the side of the bridleway and Bumblebees and Brimstones are on the wing. Pussy Willow is dusted with sulphur coloured pollen and is attracting lots of insects.

Chiffchaffs are pumping out their monotonous onomatopoeic songs, Cetti’s Warblers are setting up territories and are much easier to see while there are fewer leaves in the hedgerows.

| Song Thrush in early morning sunshine (c) Bark |
Song Thrushes, Chaffinches and Reed Buntings are all singing and pairing up. Great Spotted Woodpeckers are drumming from Roman Road and we found at least five in the same vicinity drumming, calling and presumably competing for nest sites.

The ”hotspot”
on the reserve shifts with the seasons and Big Otmoor and The Closes are
currently the prime places to spend time scanning and searching. Golden Plovers
are at their highest numbers and there are several flocks of over a thousand
with one that must number over three thousand. 
Goldies en masse (c) Bark
It is difficult to separate them,
but we noticed that one of the flocks appears to contain more individuals that
are moulting into summer plumage than the others. Perhaps just coincidental or
a group from a different breeding location? The Plovers are very restless and
jittery, flushing en masse at the slightest threat. They are also very vocal, keeping
up a continual chattering when on the ground and making alarm calls when they
flush.
Goldies with Lapwing and one Dunlin (c) Bark
They flicker gold and white as they wheel and bank, sparkling in the
sunshine, flying in tight formations when threatened and forming loose chevrons
as they descend once again.
Goldies (c) Bark
There have
been up to thirty Dunlin feeding around and amongst the Golden Plovers on both
big Otmoor and Closes they are less flighty and settle more rapidly if they
have been alarmed. Redshank are calling and displaying across the whole site as
are Lapwings. 
Displaying Lapwing (c) Bark
The first Lapwing nests with eggs are usually found towards the middle
of March. On a survey earlier this week, we watched Curlews doing their
distinctive display flight, where they fly up with shivering wings and almost
stall before gliding down and then flying upwards again. The whole display
flight is of course accompanied by their distinctive and evocative curlew call,
that for the next few months will be one of the signature defining sounds of
Otmoor.

Once again there
are two pairs of Common Cranes on and around the moor. The pair that
successfully reared a youngster last year have returned alone, and both pairs
are keeping well away from each other. One pair can sometimes be seen feeding
on the northern side of Greenaways or from the second screen on the reedbed
bund. For very large birds they can remain out of sight for considerable lengths
of time!
Marsh Harrier over the reedbed (c) Bark
Marsh
Harriers are displaying over the reedbed and this year again there appear to be
two females with a lone male in attendance.
Hen Harrier (c) Bark
The Hen-harrier is still being seen
but unpredictably and sporadically now that the Starling roost has dispersed. A
Barn Owl has been seen out and about in the early evening and early mornings.

This crepuscular behaviour is much more likely when there has been steady rain overnight, making night time hunting more difficult. Tawny Owls have been heard calling in the Roman Road and there is still at least one Short-eared Owl present in the wider Otmoor area.

There is a
lot of courtship and breeding activity from the wildfowl. Although Wigeon do
not breed on the moor they display and pair up whilst here and drakes can be seen
displaying to females. 
Pochard showing his ruby red eye (c) Nick Truby
The Pochard that are one of our breeding species are
very busy in their courtship rituals the males showing a bright ruby-red eye. “Luke”
seems to have moved away as we have not seen him for some weeks. An early visit
from a pair of Garganey for one day, was probably a pair that was moving
through rather than one of our breeding pairs.
One of six Oystercatchers present (c) Bark
Male Bitterns are starting to tune up their booming with a series of practice grunts and croaks but are not yet into their full-on booming calls, that carry across the moor during the spring.

During the
next few weeks migrants will start to arrive in greater numbers and the
Redwings that are currently feeding in the fields will depart for the north and
east. It is a very exciting time of year and it is always good to hear a new or
different species adding its voce to the Otmoor soundscape.
Grass Snakes are showing along the bridleway. (c) JR
