Early Autumn Passage

Late July movement

Barely had the metaphorical ink dried on my last post and the very next day it felt like autumn passage got into full swing!  The write-up has had to wait until now though as soon after I went on holiday and got back to busy-ness thereafter.

On the morning of 8th July 8 Green Sandpipers were reported so for my evening visit I had in the back of my mind that a sudden influx like this could come with a Wood Sandpiper too.  Not finding one, I had begun to pack up to leave when a wader hunched at the edge of a pool drew me back for a second look.

I had initially dismissed it as another Green Sandpiper but something about its head shape didn't quite seem right for that species.  The light was poor so I couldn't really see much else but as I continued watching so it began to feed and I realised I had a Wood Sandpiper!  Eventually it walked out of the glare and allowed the somewhat grainy record shot above. 

Other passage on 8th was also evident with an increase in gulls, including a Mediterranean Gull and a surprise early Common Gull through.  The first juvenile Black-headed Gulls also made an appearance.

Waders continued to feature during the rest of July but in a somewhat muted way.  It has officially been a poor breeding season for the Little Ringed Plovers with just a second pair raising one chick from 18th July.  This means that, in total, only three new Little Ringed Plovers have hatched this year from 2 pairs with likely less than that making it to adulthood.  It's difficult to pinpoint why it's been a poor year for them but it is likely to be a combination of disturbance at key moments in their breeding cycle and loss of habitat due to quarry restoration.

Green Sandpipers have been present throughout July, averaging about 4 birds on site with 2 ringed individuals and 2 unringed birds regularly being seen.  A Common Sandpiper appeared on 15th July and was joined by another on 19th, with a maximum of 3 counted on 27th.  Another Wood Sandpiper was seen briefly on 20th with another heard but unseen on 27th.

A Greenshank put in an appearance on 25th and an Oystercatcher on 29th.  Despite the substantial areas of exposed mud and seemingly ideal wader conditions the offering feels a little paltry for this time of year.  However, it is still early days...

Away from the water, interest included a high count of 4 juvenile Stonechats on 25th and an evening count of 167 Ring-necked Parakeets heading over the site in small groups to their roost at Stanborough Lakes.

Also flying over the site were 2 Peregrine Falcons on 26th, the first Siskin for the year on 27th and the first 3 Ravens for a while on 28th.  The site year list for 2025 now stands at 121 species.

Early August continues the theme...

Perhaps the most noticeable change with the new month is the arrival of large numbers of geese.  As in previous years, this seems timed to coincide with the harvesting of the cereal crops.  The goose flock on occasion has grown to almost 500 birds, among them up to 300 Canada Geese, 120 Greylag Geese and a maximum count of at least 57 Egyptian Geese on 10th Aug.

A Barnacle Goose was found with the flock on 7th and seen subsequently on and off.  The goose flock is very mobile, switching between the fields and the water and sometimes vacating the site altogether, however numbers are highest in the evening and early morning.

The first Wheatear appeared near the farm on 1st August and at least 3 were present on 14th with one seen the next day too.

In the same vein a Whinchat was found on 10th August behind the middle pool and seen again the next day - the first site record for the year.  Stonechat numbers peaked at 6 or more on 10th - all scruffy juvenile birds.

Wader passage has been almost non-existent with Green Sandpipers remaining on site but the last 2 Common Sandpipers being seen on 7th.  More noticeable has been the passage of hirundines with several flocks of House Martins (100+ on 12th) moving east with a few Sand Martins.  Swifts are also still passing through with at least 50 noted on 12th but these will be some of the last birds this year no doubt.

Yellow Wagtail passage is also underway with at 10 birds being regularly seen in horse paddocks near the farm.  Both Sedge Warbler and the site's first Reed Warblers of the year have been noted at the back of the main weedy area.  It is likely these are passage birds although it is possible they may have bred on site unnoticed.

Perhaps the most notable record for the first half of August has been the sighting of 3 Marsh Harriers together by one observer on 13th.  The sighting involved 2 adults calling and being followed by a juvenile bird.  Harriers are certainly on the radar as they disperse post-breeding and who knows, maybe a Montagu's Harrier will come our way!

Much of the autumn remains to come and hopefully the best bits too!  It's always tricky to work out why some years are quieter than others but, given the seemingly ideal conditions, the last 2 months have not delivered the hoped for wader passage.  It is difficult to know if the ongoing quarry restoration works play a part with landscaping and new topsoil being put down - perhaps on top of formerly good feeding areas.

The 'deep pits' have been reduced to a small lake and it remains to be seen if these will be attractive to birds.  Since the new topsoil has gone down these pools have been devoid of birds other than loafing gull flocks.  The middle pool has virtually dried up while the main pit has been given an extended life as water has been pumped into it temporarily.  It too faces the same fate however with further landscaping set to greatly reduce its size.  Let's hope what is finally left recovers to attract birds and wildlife again but for the moment you can't help feeling that the site is in decline.
