A day in the reed bed

With the changing seasons things have really started to pick up pace at the reed bed site at Cranwich. Reed warblers have returned in force and their song can be heard all over the site. In the past few weeks ringing has resumed with the most recent session catching a range of returning warblers, from those reedies to sedge warblers, garden warblers, blackcaps and chiff chaff. While nesting amongst the reeds has largely been restricted to coot, moorhen and swan it will not be too long before the first reed warbler nests are active once again. 

This morning mother nature seemed to have sent a little reminder that things are still early and that despite the warm sunny days we have experienced of late, winter has not quite completely finished with us. It is not quite swim suit weather just yet...

The morning dawned frosty with opaque white crystals covering the grass and the thermometer reading a rather chilly -1. Mist hung low over the pools and there was barely any wind, with the only movement coming from the small ripples created by ducks, swans and the occasional goose gliding gracefully across the smooth, dark surface and through the swirling mist that quickly began to rise like steam off a hot bath.

At this cold hour of the morning there is little in the way of food for birds awoken by the dawn. Instead they sing. Proclaiming their newly established territory, competing with each other in the most melodious of ways. Among the reed warblers and reed buntings that dominate the chorus of the reeds comes that wonderful call of cuckoo; it is a relief to have them back on patch. From the surrounding trees comes the song of garden warbler, blackcap, chiff chaff, blue tit and wren. 

As the morning progresses and warms up, the skies become filled with swifts who have only just returned to the party and join the swallows and house martins who have been back for a couple weeks. Low over the tallest trees those sickle shaped swifts are joined by another, larger bird with a similar pointed wing appearance. Skimming the tree tops, before circling back up and around, high above the pools are no less than eight hobbies. They streak through the sky chasing down flying insects with acrobatic ease and superb speed. They zip overhead causing us to pause in our work and watch in awe as occasionally one reaches out and grabs an insect that is invisible from ground level. 

A hobby catches a meal mid air

Our work today is to move through the reed bed setting up short mist nets to catch those singing reed warblers. A part of the ongoing study on site our aim is to catch and colour ring as many adult reed warblers as possible, so that once their breeding season does kick off in earnest we will be able to monitor nests and find out which birds are associated with which nests.

A hobby

A hobby - an activity or interest pursued for pleasure and relaxation and not as a main occupation.

For me, as many people will know by now, its bird ringing. For those reading the Wild Barley blog on a regular basis (thank you!) it’s pretty much impossible to escape the fact. Most weekends, and occasionally during the week, you will find me getting up ridiculously early in order to go and catch birds, to age them, sex them, take a load of biometrics and to ultimately learn more about them. The ringing I do as part of the BTO ringing scheme is contributing masses to our understanding of bird ecology and populations. Understanding how and where they moult, breed, migrate, over winter, live, grow, behave…

My hobby - bird ringing

A hobby – a fairly small, very swift falcon with long narrow wings, specialist aerial feeders.

Oh what a bird! So awesome that even a popular table football game is named after it…. Ever thought how Subbuteo got its name...? well the scientific name for hobby is Falco subbuteo and the games creator was a big fan of this super bird.

Acrobatic and fast… soaring skywards before diving back to earth; racing over treetops or reed beds; twisting and turning in mid air in pursuit of dragonflies and sometimes small birds. No time to stop, with captured prey often eaten on the wing. The delight of warm summer evenings and a highlight of any days birding; winter sees them head off to Africa in search of more insects…

When attempting to catch swallows and martins at a roost however, the hobby is not necessarily the sight you want to see. The gathering flocks provide a tempting source of food for hungry hobbies especially when migration is nearing. Storming into the group, the hobby races after the sand martins and swallows, dipping, diving, twisting and turning… the martins and swallows flock closer together, with reactions so quick they seem to move as one, confusing the hobby, not letting it single out one individual.

In many cases the flock will move on, deciding the reeds they were attempting to roost in may not be safe enough and leaving the ringers with empty nets… on top of that catching a fast moving hobby in mist nets is tricky to say the least…

Although, there are those occasions where the right factors come into play, the fates align, one little thing leads to another and you come round the corner to find not a hobby bouncing out of the net and making a quick escape, not a hole indicating where a hobby has burst through the net, but a hobby caught in the net!

With dusk falling over the reeds and nets at Icklesham, Sussex, and just a single swallow caught in the roost, it was indeed an absolute delight to catch one of these superb birds. 

A hobby - the bird :)
