Dusk at Dawlish Warren

Posted on March 2, 2010

This recording was made at dusk, on the edge of the Bight, a shallow area of tidal water on the inland side of Dawlish Warren NNR. The 23-minute long  clip covers a period from just after sunset until twilight - the original was several minutes longer, however I have removed sections where railway/aircraft/road noise became a distraction.

As the recording begins, the sun has just dropped below the horizon, and a Blackbird is still singing in the scrubby bushes on top of the sand dunes. Although the air is perfectly still, recent bad weather has left the sea quite rough, and the pounding of the waves on the far side of the dunes forms a constant bass rumble. As Herring Gulls stream overhead on their way out to sea, small groups of Curlew and Redshank begin to drop into a roosting site about 100m away along the water's edge. Just after the 7 minute mark, one of the Brent Goose flocks that winter on the Exe Estuary flies in and lands in the distance.

As the birds continue to arrive, and the rising tide shrinks the roosting space available, occasional scuffles break out. Eventually,  at 12m 39s, something causes most of the roosting birds to take to the air and circle before settling again. Peace returns until 17m 40s, when a Blackbird begins to give an alarm call, almost certainly in response to an approaching hawk. The hawk (from its size probably a Sparrowhawk, although Peregrine seems more likely in that habitat) actually flies past the microphones at 18m 21s, the rush of its wings just audible above the surf. I was sitting on a driftwood log just behind the microphones, and the bird passed by at eye level about 2m away, just a grey ghost in the twilight. Although the birds don't take flight again the presence of the hawk seems to unnerve them, and both the Redshank and Curlew are very vocal for the last few minutes of the recording.

If you're wondering what the quiet sizzling and popping noises are right through the clip, it's not the microphones acting up in the cold, damp air (the aluminium tripod was running with condensation when I finished recording) but the tide creeping in across the mud. By the time I packed up and left the water was only a few inches from the feet of the tripod!

Willow Warbler

Posted on April 25, 2009

A few weeks ago I picked up a Sennheiser ME66/K6 combo at a bargain price on eBay. The ME66 is a short shotgun microphone capsule, which fits onto the K6 power unit. The K6 runs off 48v phantom power or from a single AA battery, meaning the microphone can be used with any of the smaller audio recorders which don't supply phantom power. The microphone makes a nice light-weight alternative for when I don't want to carry around my NT1-A stereo rig. It's mono only of course, but unless you have over £2000 to spend on a Sennheiser MKH30/40 mid-side pair, you're not going to find a low-noise stereo solution that fits into a single Rycote windscreen.

To test the mic out, I took it to our local nature reserve, Dawlish Warren NNR. It was a beautiful Saturday afternoon, and the reserve is immediately behind a popular tourist beach, so most of the recordings came out with a lot of human noise. After walking around for a bit I found this Willow Warbler (Phylloscopus trochilus) singing in a clump of birch trees. You can just hear some quiet conversation from the nearby golf course, and an occasional vehicle, but these are drowned out by the incredibly powerful song of the warbler, which was a good 20m from the microphone. Also audible are Rook (Corvus frugilegus), Blackbird (Turdus merula), Blackcap (Sylvia atricapilla), Blue Tit (Cyanistes caeruleus), Herring Gull (Larus argentatus) and Linnet (Carduelis cannabina).

Dawlish Warren Pond

Posted on March 21, 2009

This was recorded at around 06:45 this morning, after a failed attempt at dawn chorus recording. Possibly the fact that it was the coldest night for several weeks had put the birds off, as there was virtually no song in the woodland surrounding this small pond at Dawlish Warren NNR. At least the waterfowl did their best to make up for it...

Species include: Little Grebe, Mallard, Canada Goose, Herring Gull, Woodpigeon, Blackbird, Chiffchaff, Greenfinch, Magpie and Carrion Crow.

Recorded with a Tascam HD-P2 recorder and two RØDE NT1-A microphones in a custom-built ORTF array with a central barrier. Filtered to remove vehicle noise and boosted by 6dB in post-processing.
