Bird project 29 - Barn owl

30/101.
Tyto alba Barn owl

Location: Roosting/nest box on island, NE corner of Marton Mere, Blackpool (my location was the embankment path to the east).
Conditions: Late afternoon, through dusk into the early night. Bright, light cloud; persistent breeze; cold, becoming very cold indeed after dark.
Photograph quality: n/a; video only (equivalent to 3); note, there's a lot of noise due to high ISO, and although I've applied heavy vibration reduction, the shot still waves about quite a bit, as the wind caught the huge lens (the tripod I use is really not designed for this sort of thing). Still, you can make out the bird(s).

Comments: I staked out the box a few months ago, but with no luck. I tried a technique I'd not used before, using the camera and long lens mounted on a tripod, filming in HD, as I knew any glimpses would be brief, and it would be typical that I'd be looking away when it happened. This way, I could review any activity at home, speeding up the footage. I tried this method again today, as a couple of birds (possibly including an unseasonal juvenile) had been seen in the box regularly recently, and the weather was good (almost mild earlier in the day, and bright and dry, although the cold wind really bit later on).

There are a few advantages to video over stills in this case. First, the nest box is too far and inaccessible to allow any reasonable quality shots - even at 1400mm, it is small in the frame. Second, video works better in low light, as you can use much longer exposure times per frame (as slow as 1/30sec if shooting at 24fps) without worrying about blurring (as this is acceptable in video frames, but not for stills), and since the sensor is downsampling from 22MP (in the case of my camera) to 2MP (full HD), noise even at the highest ISO (25600 for video) isn't as obvious. Since these birds are active at dusk, maximising light is a priority - especially since I needed to keep as much focal length as possible (I started at 1400mm, only swapping down to 1000mm and finally 700mm when the light had almost totally gone). Still, it would be nice to try out the Canon C100 or C300 cameras, which now do ISO 80000 (even higher than the 1Dx's maximum of 51200 for video). Getting any kind of good shot is probably not possible at this location, sadly.

So in this footage you see one bird preening itself, looking out a little (first video), then a second showing its face, and doing some strange head bobbing (it also turned its head nearly upside-down, in that special owl way) in the second video. It was good to see wild ones at last - I saw a captive bird a couple of months ago, close up, but this is just as special.  I've included some screen grabs in case you don't want to sit through the videos.
