My fellow blogger Steve Gale recently published volume one of his natural
history memoirs. Steve is only a few months older than me, so his wonderful
account of discovering birds and serving a birding apprenticeship through the
1970s resonates powerfully. It doesn't matter that my own journey didn't begin
in earnest until a few years later, Steve's descriptions of Beddington,
Staines Reservoir and Dungeness take me straight to these places, in all their
sepia-toned glory. And it is to the Dungeness of Steve's memory that I would
like to travel now, one August day in 1977...
Steve's account relates the discovery of a Hippolais warbler in
the Dungeness Observatory moat. Upwards of a dozen birders are gathered,
trying to decide whether it's a Melodious or Icterine Warbler,
and among their number is the late Peter Grant. Steve justifiably describes
PJG as a 'birding god' of the day. The Dunge Hippolais crowd
awaits PJG's judgement and, after ten minutes watching it, he pronounces the bird a Melodious Warbler. Which obligingly then enters a
Heligoland trap and reveals itself to be an Icterine Warbler, a fact
which PJG takes in good part, and uses to teach a salutory lesson to the
gathered young birders...
I shan't say what that lesson was - though likely it's pretty obvious - rather
I'll recommend you download Steve's book (find it HERE) and discover for yourself. But I'm going to nick Steve's anecdote to illustrate a
bird identification truism: even the best can get it wrong.
On Twitter just
lately I've come across a couple of interesting ID conundrums which bear
talking about in this context. The most recent was a set of flight shots of a juvenile gull. The
identification came down mainly to a choice between
Yellow-legged Gull and Great Black-backed Gull, with votes in
favour of both, but even Lesser Black-backed was mooted. In the end the
correct ID was GBBG, but it was very refreshing to see a number of
birders get involved in the discussion and offer their opinions. Hats off to
them all, because on a public forum like Twitter I think it takes bottle to do
that. The risk of getting it wrong is very real, and though few have a
reputation like the late Peter Grant's to 'worry about', no one actually
enjoys being wrong.
For the second example I first need to reference a photo I posted on Twitter
last year. Back in May 2020 I spent a lot of time peering at the sky from my
garden. On a day which produced a few Red Kites I also had a rather
tatty falcon. It wasn't close, but through bins I identified it as a
Peregrine. I got a number of tenth-rate photos, but reviewing them
later made me change my mind about the bird's ID. I decided it was actually a
first-summer Hobby...

If your reaction to this photo is, 'What was he thinking?!' well,
yes...exactly.

No doubt my reasons for revising the identification were clear at the time,
but anyway... Very quickly a birder on Twitter put me straight, kindly and
tactfully suggesting it was a first-summer Peregrine. And of course, he
is correct. Somewhere on my Twitter page that faux pas still lives, and
it's a lesson I've not forgotten. So, when a Devon birder named Jo King posted
the following on Twitter just recently, I felt I ought to grasp the nettle...
I believed Jo had made the same mistake I had, and been hoodwinked by a young
Peregrine. Obviously I could have simply thought my thoughts and kept
them to myself, saying nowt. But I've learned lots of useful ID stuff through
Twitter which I feel has helped me develop as a birder, and saw this as an
opportunity to reciprocate. So I did. Unfortunately I hadn't anticipated one
or two other experienced birders endorsing Jo's original identification, and
giving some reasons why it was indeed a Hobby. Suddenly unsure of
myself, I backed off and looked at the photo more carefully...

I really couldn't reconcile the broad-based wings and fine, dense streaking on
the underparts with Hobby, but it's quite easy to doubt yourself
sometimes, especially when presented with a seemingly confident alternative
view. One thing I will say though: it did make me get the books out and do
some online research! Thankfully, before I got too despondant about my evident
inability to ID falcons, some other experienced voices joined the discussion.
The bird is indeed a young Peregrine after all, and there are several
good reasons why. One interesting point which came out is that
Peregrines on sandstone cliffs (as is frequently the case in Devon)
often wind up with a rusty-stained vent area. In a nutshell, I learned stuff,
and was glad I'd got involved.
I've wanted to write a post like this for some time, and Steve Gale's
wonderful anecdote about Peter Grant and the Hippolais warbler
helped crystallize my thinking. Bird identification is not easy, and in some
cases very tricky indeed. We all get it wrong sometimes, and every one of us
is still on the learning curve. Despite that, there are some brilliant
teachers out there. Peter Grant may have been a one-off, but there are many
birders whose particular interests (or should I say passions?) make them
relative experts in their field. It's brilliant to see some of them willing to
share that expertise online.
My recent experiences on Twitter are very heartening. It's lovely to see
birders responding to ID queries, willing to stick their neck out, willing to
give reasons for their opinion. And it's lovely to see a bit of
humility too. And when someone like me (or Jo above) posts an incorrect ID
it's great to see tactful efforts to put us right. In the end, we all gain I
think.
Finally, because the photos posted so far depict only Peregrines, I
thought it might be useful to post a collage with some Hobbies in the
mix. Apart from Jo's photo they're all mine, and therefore pretty dire. Even
so, hopefully they illustrate that when seen side by side, the two species
aren't really too difficult to tell apart. But then you remember that both
species show considerable variation in size, have age-related plumages, and generally come one at a time. And that Merlin is a
thing.
