Oxon Birding Weblog: Summer time overview

Highlights

The lean interval, the summer time lull or the summer time hunch –
no matter you name the June – July interval, birding the months wedged between the
Spring and Autumn migration intervals is a a lot quieter and centered affair. It
generally is a nice time to understand the comings and goings of our native breeding
species that we might typically take with no consideration in the course of the busier months.  Numerous us will even use this era to catch
up with among the rarer Orchids, Lepidoptera and Odanata of which Oxon and
the encircling counties host in abundance. For people who do concentrate on these
different taxa, rewards can sometimes come within the type of among the rarer
migrant species with 2024 producing a document breaking variety of Lesser
Emperor for the county. Others will concentrate on the fortunes of our
uncommon and scarcer breeding species, notably Waders which might, to say the
least, be a mildly miserable exercise – talking from my very own expertise of
monitoring our native breeding Curlew this 12 months.

Rarities, of the avian selection, are typically only a few and much
between. That being mentioned, wanderers do sometimes stray into the county borders,
see the Black-crowned Evening Heron on my very personal patch final 12 months, however
2023 sadly didn’t produce something on this degree. A short coronary heart
palpation second got here when an unconfirmed report of a Purple Heron at Otmoor
on the 19^th however remained a thriller with no additional sightings. The
arrival of our first returning passerines from the latter a part of July although
indicators a altering of the seasons with each Whinchat, Redstart and Willow
Warbler famous. While I acquired a pleasant shock when surveying simply different the
border in Bucks, when a male Wheater popped up on a fencepost –
the unstoppable march in direction of Autumn has begun and we will all now look
ahead to a busier interval of native birding!

Waders

The standout of the interval got here with the primary returning Wooden
Sandpiper again Pit 60 on the 27^th. At all times a well-liked
species after they flip up this one had a string of admirers throughout its keep
till the 29^th earlier than it departed in a single day.

Sanderling had been
recorded in each of the summer time months with a single chicken current at Farmoor on
the 5^th June and apparently nonetheless current by the ten^th.
A late northward certain migrant or a failed breeder returning south, who is aware of!
A chicken current additionally at Farmoor on the 22^nd July,
appeared a lot clearer, with probably the identical chicken nonetheless there on the 28^th.

A lone Whimbrel document got here from Farmoor on the
5^th June and was seemingly on path to the north, though in
current years lone birds have linked up with failed breeding Curlew flocks
across the county. Greenshank had been additionally recorded in each months with a
chicken at Widford on the 14^th June while a primary returnee got here
on the 4^th July at Ardley remained till a minimum of the
11^th.

Black-tailed Godwit had been first famous within the county at Peep-o-Day
Lane on the 7^th July the place a flock of 5 took benefit of
the now fixed presence of shallow water right here. The following birds then got here
by the county at Ardley on the 23^rd July with a
pair right here till a minimum of the 25^th. The one Dunlin document
got here on the 28^th July with a single chicken becoming a member of the Sanderling
at Farmoor, while Ringed Plover had been famous at Port Meadow
on the 1^st and three^rd June and at Grimsbury on
the 28^th July, with a pair at each websites.

The primary returning Inexperienced Sandpiper got here from Bicester
Wetlands Reserve got here on the 7^th June, a really early chicken
and probably a failed breeder from the far north the place the breeding season can
be very brief affair. Three birds had been right here on the 18^th while July
noticed a excessive rely of 17 on the 25^th, with the location sustaining
its standing because the premier cease over web site for this species throughout migration. Eight
extra websites recorded between 1 and 5 birds from the 19^th June onwards,
though most information got here from the center a part of July. Widespread Sandpiper arrived
a bit later, though the primary document of 14 birds at Farmoor on the
29^th was a little bit of shock. With females and failed breeders returning
sooner than males and juveniles, it appears this flock was most likely mixture
of the latter. An additional 7 websites recorded birds by July with
wherever between 1 and 10 birds at anyone web site.

Wildfowl & Recreation and many others

Essentially the most stunning sighting of the interval got here from Farmoor
on the 23^rd when a feminine Widespread Scoter dropped in.
Presumably a failed breeder from some remote Scottish Loch the chicken
remained for the remainder of the day earlier than departing in a single day. In what has turned
out to be not a very fruitful 12 months for Quail, and definitely not
a ‘Quail 12 months’, the summer time produced solely 6 public information. Crog Hill,
a traditional summer time web site, had a single document in early June while someplace
in West Oxon noticed two birds ringed on the 8^th June. A chicken
singing alongside the Glos/Oxon border was the one chicken reported on consecutive
days reported between the 18^th and 29^th June sporadically.
Most different information got here, usually, from the Oxon Downs with a most
of three birds heard without delay at Sparsholt on the 30^th June.

A really uncommon probability to look at a Quail up shut 

With no confirmed breeding this 12 months, information of Garganey got here
from 4 websites. Otmoor, the location of breeding in earlier years, had a
single male on the three^rd June. While further single feminine
information got here from Appleford and Peep-o-Day Lane on the ten^th
June and 15^th July respectively. While Pit 60 had a pair
current within the latter a part of June, with solely the feminine then current
by a lot of July. One other uncommon breeding species that was confirmed breeding
although, got here within the type of a feminine Goosander with 5 chicks at Waterstock
on the 16^th – the three^rd 12 months such breeding has occurred.

Ruddy Shelduck made their annual jaunt into the county, put up summer time moult,
with information at Farmoor and Peep-o-Day Lane. A flock of 4 was
on the former on the 21^st July while a single chicken was on the
latter on the 31^st, the two^nd 12 months through which a chicken has
arrived on web site post-moult. Our personal native Shelduck had been recorded solely
from 3 websites in the course of the summer time months, with no additional affirmation of breeding
forthcoming from any of those websites. Port Meadow hosted essentially the most birds
with 5 right here on the 15^th June. Additional information got here from Bicester
Wetland Reserve and Peep-o-Day Lane.

Herons, egrets and many others

A report of Purple Heron from Otmoor on the 19^th
June acquired the collective coronary heart of the county going for a short interval
over the summer time. Sadly, the document was by no means confirmed and a few individuals’s
await an accessible Purple Heron within the county must stretch a
little additional! The foremost spotlight then, got here within the type of the two^nd
Spoonbill of the 12 months with one over Otmoor on the 18^th
June, with the chicken seen sporadically between then and the 22^nd
June. Issues then acquired a bit loopy with 5 possible’s over Thame on
the 29^th July, though these we not seen wherever within the
county and can sadly stay a thriller.

The Shiny Ibis that turned
up within the county on the finish of Might took an important liking to Otmoor and
remained there all the summer time, with most reviews of it coming into roost
in the course of the night vigils. A lone White Stork, a now frequent customer to
the county courtesy of the White Stork Challenge, was seen all through the
county in the course of the early a part of the month. Confirmed from SatTracking to be a chicken
from the mission (ring quantity GBA9) that was born in 2023 and didn’t migrate
in its first 12 months. The chicken was seen at 4 websites together with Otmoor and Appleford
between the 6^th and eight^th June and was
apparently nonetheless current on the 16^th. An unconfirmed document of 6+
over the m40 on the 11^th was an attention-grabbing thriller document.

Each Nice White and Cattle Egret had been extensively
seen throughout the county as in earlier months with the breeding standing of the latter
confirmed for an additional 12 months. Nice White Egret had been recorded at 8 websites
with a most rely of 5 on the most common web site of Pit 60, a possible
space for future breeding makes an attempt? Three had been additionally seen recurrently at Otmoor throughout
the summer time, while 2 had been at Peep-o-Day Lane on the 23^rd June.

Cattle Egret largely saved their western distribution within the county, with the
exception of Otmoor, with a minimum of 7 websites recording birds. As much as 3
occupied nests had been noticed at Blenheim, though as in earlier years
extra had been suspected. Profitable breeding was confirmed for an additional 12 months with at
least a pair juveniles clocked at numerous websites and a put up breeding flock of
19 had been recorded at Otmoor on the 29^th July.

Crane seem to have had an unsuccessful 12 months at Otmoor, with no
affirmation of any profitable breeding makes an attempt over the summer time. This was backed
up by extralimital information of Crane coming from two websites over the
summer time, with 2 over Farmoor on the 29^th June and 4
over Woodstock on the 16^th July – presumably all 4
birds from Otmoor. Little Egret don’t typically get a point out in these month-to-month
reviews, not like their rarer cousins, however a cracking rely of 40+ birds at Otmoor
felt noteworthy sufficient to say and an indication of some good breeding elsewhere
within the county?!

Gulls and Terns

The usually quiet months saved up
their fame with only a few noteworthy information of notable species over the
summer time interval. Regardless of this, among the finer eyed amongst us nonetheless managed to
pull out the odd rarity. Port Meadow produced a possible Baltic Gull on
the three^rd June, the primary because the 2021 summer time interval when one
birder made it their mission to search out the county’s first confirmed Baltic Gull
and ended up discovering 4 – see (https://tmbirding.blogspot.com/2021/08/the-baltic-gulls-at-appleford.html).
Caspian Gull continued their run within the county, to what one can now
assume will likely be an virtually 12 months spherical presence in Oxfordshire. A lone chicken
was on Port Meadow on the 4^th June and once more on the 25^th
June, while simply up the street at a comparatively newer web site in Stanton
St John had been current on the ten^th June.

The opposite spotlight got here within the kind
of a number of information of Sandwich Tern, a extremely uncommon summer time sighting
and a presumably an indication of issues going flawed for these birds on the breeding
entrance. A trio had been current at Dix Pit on the 9^th June earlier than
been noticed simply down the street at Rushy Widespread on the identical day, albeit
minus one chicken. Curiously 3 had been additionally noticed at Rushy Widespread on
the 22^nd June and one has to imagine the identical birds, though
the place they had been within the interim stays a thriller! One other uncommon summer time document
got here from Freeland with pair of grownup Little Gull seen in flight
heading in direction of the extra typical web site of Farmoor or a minimum of in that route
on the 30^th July, however sadly birders there weren’t
capable of join with these early passage birds. The one different actual noteworthy species
this month was a small variety of Mediterranean Gull information, two from Farmoor
on the 9^th and 30^th July and one other from Pit
60 on the 27^th.

Passerines

Migration of passerines by the county started on the very
finish of June with 3 Redstart at Pit 60 on the 30^th.
Most birds although began transferring by the county in early-mid July. A
additional 6 websites noticed Redstart information with many of the websites recording
a number of birds by the center a part of the month. Whinchat arrived a
little later with the primary at Woodstock and Otmoor each on the
14^th July and each nonetheless current by the 21^st.

Different attention-grabbing information got here from Blenheim with
breeding confirmed for Stonechat, a species with a restricted breeding distribution
within the county largely confined to the Oxon Downs. Breeding Cuckoo was
confirmed throughout a number of websites with sights of the primary fledged juveniles, together with
a pleasant video of 1 been fed by a presumably knackered Reed Warbler. A
Hepatic feminine was once more at Otmoor in the course of the summer time, this been 4^th
or 5^th 12 months this identical particular person has returned to the location.

A lone Crossbill document got here from near the downs
at Lockinge, with a male right here on the 16^th July. While
it seems the Ring-necked Parakeet have had one other first rate breeding
12 months in 2024 with roughly 85 at Florence Park on the 19^th
July, the influence of that is but to be recognized however presumably the native
birds are unlikely to be happy on the prospect.

Raptors

The
main pleasure for this group in the course of the summer time season has been the enjoyment of
watching the juvenile Marsh Harrier over Otmoor after one other
profitable breeding season. The curiosity has been even increased this 12 months resulting from
two of the 3-4 younger been in a really uncommon and placing plumage. Regardless of the
birds trying like they’re leucistic, the reason for the patches of placing
white plumage apparently have a way more sinister clarification. When younger birds
are creating their fledging plumage from the tender fuzz of downy chicks a foul
weight loss program or poor climate could cause a shock to the system whereby the physique stops
producing the melanin wanted to develop regular feathers. This lack of melanin then
causes the massive patches of white plumage that may be seen by the birds
wings and physique. Sadly these feathers consequently are additionally brittle and survival
of the birds generally is a robust ask, particularly going into the winter months. A pleasant
clarification may be discovered right here – https://x.com/Au_Erithacus/standing/1817867089790578792.
Let’s hope they handle to make it, they shouldn’t be too laborious to maintain a monitor
of!

If the Otmoor reserve was to be distilled, it could be the large open skies and the wetland birds that frequent. Debbie Cowee has captured each on this picture of the lengthy staying Shiny Ibis because it is available in to roost.
