Serendipity struck on Sunday a couple of weeks ago. I’d fixed up to go for a stroll with an old friend who I hadn’t seen for a few years to Wicken Fen. That was on the 20th May, but he got his Sundays confused and we ended up going on the 13th.
It was serendipitous because the weather had been grim leading up to that weekend but on the evening of the 13th it was perfect: sunny, warm, calm and we couldn’t have wished for better conditions. And on top of that there was wildlife in abundance. As we got out the car the air was full of swifts screeching overhead – lots and lots of them – along with swallows and house martins. Various species of geese and ducks and great crested grebes (Podiceps cristatus, Dansk: toppet lappedykker) were on the lakes, and we were serenaded by cettis warbler (Cettia cetti, Dansk: cettisanger), grasshopper warbler (Locustella naevia, Dansk: græshoppesanger) and other songbirds in the undergrowth, and a snipe drummed in the reed bed. Snipe (Gallinago gallinago, Dansk: dobbeltbekkasin) make this sound by spreading their tail feathers and the wind generates the piping sound by making them vibrate.
Wicken fen is a really good place to see birds of prey too: marsh harrier (Circus aeruginosus, Dansk: rørhøg), hobby (Falco subbuteo, Dansk: lærkefalk), kestrel (Falco tinunculus, Dansk: tårnfalk), sparrowhawk (Accipiter nisus, Dansk: spurvehøg) and assorted owls can all be seen there. We had been commenting how the birds of prey were conspicuous by their absence and a few minutes later we spotted a hobby perched on a fence post. As we wallowed in our good fortune I spotted an owl behind a tree which emerged right in front of us and it turned out to be a short eared owl:
Short eared owl, Asio flammeus (Dansk: mosehornugle)
I thought our short eared owls were winter visitors, migrating to the relative warmth of the UK from the frozen icefields of Scandinavia and returning in the Spring. But it transpires they are also resident breeders in the east and north of England and the east of Scotland so can be seen here all year round.
This one treated us to several minutes worth of hunting, flying to and fro and diving down into the reeds in search of rodents.
I last saw short eared owls at Burwell Fen, east of Cambridge, several months ago when there was a large number of Scandinavian visitors in residence. While we were there we chatted to a BBC camerman who was there to film them for a TV nature series. I think he would have got some good footage on that day but I’m sure he would have been pleased to get this close to one!
Like all owls, it’s a hunter which is supremely evolved for its particular function.
And then on the journey home, continuing the owl theme, there was a barn owl taking the lazy approach to rodent hunting:
Barn owl numbers have been on the decline for a long time and the exceptionally cold winters of 2009 and 2010 badly affected them. We didn’t see one at Wicken which surprised me because I usually see at least one when I’m there at that time of the evening, so it was good to find this one perched on an advertising hoarding alongside the road home.
I’m a firm believer in serendipity playing her part in human endeavour and she adequately rewarded us on this excursion!
