Vismig calls

Here is a selection of calls I've found on the excellent xeno-canto website of the type of vocalisations I've heard species give while migrating.  If you've never given a vismig session a go before listening to these, and remembering them, should give you a great start.

Tripits

This is a panoramic view from The Pinnacle, Sandy (you should be able to scroll around it usung your mouse).  It is a great vismig spot, virtually unknown about until I started putting in some time up here in autumn 2007.

This morning it produced two Tree Pipits together about twenty minutes after sunrise - my first of the year in Beds.  I don't usually do any vismig sessions until well in to September but I am now wondering whether I should do a few more in August, just to catch the Tree Pipit and Yellow Wag movements?  Maybe I will.

Here's a recording of the Tripits from my Remembird:

The big kahuna

I arrived just before seven, and as soon as I opened my car door I could hear Redwings and Chaffinches. Hearing Redwings before dawn isn't that unusual, but hearing Chaffinches was! I made my way through the trees out on to the top of the Pinnacle. It was still very gloomy and I could hear the occasional Redwing 'seep' from the surrounding trees - or so I thought at least. I assumed birds had dropped in to the woodland to roost up over night.

Five minutes later and the light was just sufficient to pick up the first passing birds. Small flocks of Redwings were passing over west in groups of around ten. It was obvious that virtually all the birds I'd heard when still dark were passing flocks rather than pausing birds in the trees. These initial birds were all in small groups - up to twenty.

After around ten minutes Mark Gurney turned up, and I'm glad he did - the flocks were coming thicker and faster and building in numbers. A big move was on! After an hour of non-stop counting, and some huge streams of Redwings over head (the largest being c.500 individuals strong) Mark had to leave. I was then on my todd for the next twenty minutes. It was pandemonium! I didn't know which way to look next, and everywhere I did look had a flock of Redwing zipping past! Thank God Col Campbell turned up fifteen minutes later. "Anything happening?" he said - "Yes, look up!!" I shouted at him as another pile of thrushage made its way across the sky.

The pulses weren't really pulses any more, it was more like a torrent, no tsunami, of birds, flapping, gliding, and skidding north-west. This was vismig at its absolute best! My notebook was filled with scribble - numbers everywhere, with "Redwing" scrawled somewhere nearby. Virtually everything else, apart from Redwings, were ignored - I heard a Crossbill, but didn't bother looking for it, and I also heard at least three Bramblings amongst the melee of fizzing Redwings. And a Raven, I saw fly right past the watch point, I almost never even pointed out to Col!

Back to the Redwings. It was rapidly heading towards 9am and time for work. I'd tried to get Matt Burgess to come up, but he was busy. I'd also tried Mark Thomas, but he never answered his phone. Luckily Mark phoned back and I let him know what was going on. He joined us within a few minutes. The passage at this point were about at their strongest, with lines of Redwings snaking across the sky, making counting difficult. Three pairs of eyes were just about right - one for looking south, one for looking north, and the other (me!) to scribble everything down and keep an eye on what's going above us. However, Col and I had to go to work. We passed MST the baton and hoped he could keep up!

When I got in to work, a quick tot up of our numbers revealed a staggering number - 21,551 to be precise! Obviously a group of about 500 went down as '500' so the extra one is a bit silly. Either way, it's still A LOT of Redwings!

Mark by this time had persuaded Matt to join him. They kept the pace going and had the best birds of the morning - Ring Ouzels! They had five birds fly over them during their middle hour of obs. Gutted I missed them, but a superb record, and a first for The Pinnacle. By the time 11am had come around the passage had almost stopped. The guys had counted another 7000+, bringing the total for the day (06:55-11:25) to 28,982.

However, the story doesn't stop there. Johannes Kamp, who lives in Sandy, just below the watch point, also had another load of birds just before dusk. He counted 4006 birds between 17:40 and 18:46 when it got too dark to count further. I wonder how many more we could have added if someone was on the Pinnacle?

So, grand Redwing total for the day - 32,988!

Cosmic.

Loony vismiggin'!

This isn't what you usually expect to see vismigging in the middle of Bedfordshire! This Diver, which I'm pretty sure is a Black-throated, flew over a few minutes before I was about to leave for work.

I wasn't quite sure what I was looking at when I first picked it up as a dot off to the north-east. As it got closer I thought 'grebe?' but after a few seconds more it was quite plainly a diver! It's not often to have to identify divers from underneath, so I couldn't put a name to it initially. It was only after viewing this on a TV at home this evening I could piece together what I saw:
* Smalli-ish Diver, not as bulky as a GND
* Slim neck with obviously sticky-out and bulbus head
* Obvious feet and legs sticking out the back
* Quick-ish flight
* Not startlingly white, like Red-throat

In addition to the Diver I also had three probable Woodlarks fly over, but were just a bit too far away to confidently identify. Anyway, the rest of the session was fairly productive too...

07:00-08:30
Most movement was north this morning, quite different to the usual south
and south-west. In order of appearance:

Meadow Pipit - 23
Chaffinch - 74
Dunnock - 2
Redwing - 26
Goldfinch - 7
Yellowhammer - 5
Pied Wag - 10
House Martin - 4
Sparrowhawk - 2

Vismig from the Pinnacle

This is the Metcheck jet stream chart for today. I guess the good movement of today was mainly due to the south-westerly winds pushing stuff lower in altitude so we could see it?


08:00-11:00
Low cloud and fog slowly cleared to reveal a patchy blue sky. Movement was west unless otherwise stated.

A good morning, unfortunately I was slow getting up as a cold has hit! 2305 individuals counted migrating (not including the GP's). Virtually all of the Fieldfares were passing over very high, which made picking them up very difficult, the count is of only 10 groups, with the largest being 90 birds. Wood Pigeons have also just started to move here, with virtually none seen moving before today from the Pinnacle. Lots of Chaffinches, with most just singles and pairs, with the odd larger flock. Starlings were also prominent today too, with the largest flock being 80.

Redwing - 998
Chaffinch - 407
Fieldfare - 222
Starling - 261
Wood Pigeon - 260
Redpoll - 3
Reed Bunting - 3
Brambling - 5
Snipe - 1 NE
Meadow Pipit - 24 S
Greenfinch - 26
Yellowhammer - 2 S
Grey Wagtail - 1 S
Siskin - 5 S
Goldfinch - 6 NE
Bullfinch - 5
Skylark - 24 S
Blackbird - 3
Pied Wagtail 3 S
Stock Dove - 1 S
Linnet - 12 S
Song Thrush - 7
Lapwing - 16
Dunnock - 2
Herring Gull - 3 S
Lbb Gull - 5 S

Also c.700 Golden Plovers which were milling around, flying up and down the valley and a Raven over north-west.

Wind: light, north-east
Cloud: 8/8 with a period of roughly 5/8 in the middle of the watch.

Possibly the strongest passage of Chaffinches we've had so far watching from the Pinnacle. One of the highlights was the Merlin which shot after the first three Redwings of the morning right over the Ivel valley!

More on The Pinnacle

Here is a Google Maps interactive image of The Pinnacle at Sandy, Bedfordshire. There is a bench just about under the pointer where we stand and watch 'vismig'.

Vismig on The Pinnacle

Spent a very enjoyable lunchtime on the Pinnacle today. Everything was flying west, unless otherwise stated:
Redwing - 637
Chaffinch - 74
Brambling - 3
Song Thrush - 1
Siskin - 1 NE
Meadow Pipit - 7
House Martin - 17 S

Below is the Metcheck jet stream chart for today. No wonder we got a rush of Redwings today!

The Pinnacle, Sandy

Here are two views from The Pinnacle (also called locally the Sand Hills) from where I look for visible migration, or vismig for short. I started last autumn and did a few days here and there, with two exceptional ones. On 2nd November 2006 we had around 8000 birds fly over us in around two hours. This included over 5000 Fieldfares and 2500 Redwings! Outstanding counts for Bedfordshire. The next day we saw around 2500 birds, which was still a fantastic mornings birding.

This autumn (2007) we are doing the same again, but hopefully spending a few more mornings 'on the hill'.
