After a painfully quiet few weeks the patch returned to form
in style this weekend, with a long overdue year tick and an excellent, varied
autumnal vis-mig session making for a memorable couple of days. The year tick –
number 117 for 2017 – came on Saturday when a Hawfinch flew west over the New
Barn footpath.

Hawfinches are rare visitors here, and on Sunday morning it
was clear plenty of birds were moving (largely) south-east. I finally got my
first Redwings of the autumn (10 in total), as well the Hawfinch, and an
enjoyable mix of other species. My main watch was at New Barn, and the totals
in an hour and a half were 5 Lesser Redpolls, 28 Siskins, 3 Grey Wagtails, 3
House Martins, 2 Yellowhammers, 56 Meadow Pipits, 16 Herring Gulls, 44
Woodpigeons, 48 Chaffinches and 2 Pied Wagtails.
Despite all the above, the standout moment of the weekend
was something else. In fact, I’ve struggled to get it out of my head since it
happened. At 07:53 on the Sunday, whilst walking the New Barn path to my
watchpoint, I was stopped dead in my tracks by a very unusual Pipit call. It
was clearly not a Mipit, and was a sound that didn’t instantly connect with
anything in my mind, causing slight panic mode.
I struggle with separating the less common Pipit calls, but
Meadow and Tree I easily pick out. This call simply didn’t come close to matching
anything I could think of, including Water/Rock (I find these 2, and Meadow,
very similar) and Richard’s, as well as the regular 2 species over here. It was
drawn out, clean sounding and, most notably at the time, very unfamiliar.

I called the boys up the Tower, and had a chat with Wes who,
based on my description, suggested Red-throated. However, I still tried to
dismiss a rarer option, convincing myself it was Tree. I hadn’t had one over
for about a month, maybe I was just out of tune? I played Tree on my phone, and
at that point became very uncertain. However, because of the activity in the
skies, I put the bird somewhat to the back of my mind.
Back home and over breakfast, I went through a few Pipit
calls, and I nearly spluttered my coffee out when I played Red-throated. That,
surely was what we heard! My girlfriend remains adamant that Red-throated is
the call she heard and, in her words, the sound was “longer, clearer, less
buzzy and a little piercing”. As time has gone on, and I’ve recalled the moment
and listened to calls countless times, I’m honestly left feeling that it was probably a
Red-throated Pipit, and I’ve tried to summarise why below:
- The call was something totally unfamiliar to me - I like to think I'm good with flyover bird calls, and this instantly threw me.
- If it was Tree, which I tried to make it, then there'd have been no confusion and I'd have called it from the off.
- Red-throated don't sound like Tree Pipit's really, certainly to the trained ear, and what I heard didn't really sound like a Tree Pipit.
My only frustration is that I didn’t play Red-throated at
the time, or even after Wes suggested it. If I had, with the sound I heard
fresher in my mind, I may have been able to make more of a connection. It might
seem crazy, but for me that bird was a possible/probable Red-throated.

I’ll blog in more detail about this soon (though it’s
essentially a deeper examination of the Hascombe Gap theory), but look at the picture
to above and to the right. The High Weald ridge stretches from south-central Hampshire (near
Waterlooville) to the north Kent coast (near Gillingham). There’s one obvious
gap, marked by the black mark (the River Mole at Mickleham is also a notable
gap, though not as expansive). Prominent avian access/departure points Climping,
Beachy Head and Dungeness are marked red.

Now examine this closer, clearer topographic map. The
prominent gap in the vast High Weald is again (roughly) shown by the black mark. This
gap, with the Arun flowing up to just beneath it, and the Wey flowing to just
above it, is surely very appealing to migratory birds. That black mark? My
patch!
