Meadow warblers

Posted on September 4, 2013 | 15 comments

Our migrant warblers were all back from Africa and nesting by the beginning of June. There are four species which normally frequent my local countryside, the blackcap (Sylvia atricapilla, Dansk: munk), chiffchaff (Phylloscopus collybita, Dansk: gransanger), willow warbler (Phylloscopus trochilus, Dansk: løvsanger) and the whitethroat (Sylvia communis, Dansk: tornsanger).

The blackcap have been conspicuous by their absence this summer. The central European winter population, of which a pair took up residence in the garden last winter, disappeared in the spring and that was the last time I saw one. Chiffchaff were, as always, the first winter visitor I noticed returning because of their characteristic song calling out from the trees. There are several other birds singing in the background here but the call of the chiffchaff is clear above the others, and it’s easy to see where it gets its name from.

It’s now at the start of September and I haven’t seen a chiffchaff for a while, but through the summer I regularly saw willow warblers which were nesting in a bramble thicket that I passed when I was out walking the dog. Willow warblers are very easy to mistake for chiffchaff by sight but willow warbler song is quite different.

The song isn’t the only diagnostic differentiator between these two species, there are a couple of others but they are more subtle. The most noticeable is the colour of the legs, chiffchaff have dark, almost black, legs and the willow warblers are red brown. Differences in plumage of the willow warbler are the brighter stripe over the eye (the ‘supercilium‘), a more promounced dark eyestripe and the patch under the eye (the ‘ear covert’) is olive grey with a pale patch immediately below the eye, compared to the more uniform dark grey colour of the chiffchaff. So if you get a good look through binoculars it’s not too difficult to tell them apart, but the song is the easiest way.

Pausing to check up on me before heading into the nest

For a couple of weeks there was a spot in the field where I could stand close to the nest and watch the comings and goings of the adult willow warblers bringing food for the youngsters, and they seemed cautious but otherwise content for me to be there if I stood still.

Whitethroat male – my best ever bird portrait!

My favourite warbler is the whitethroat. They are easy to tell at a distance, even without optical assistance, and this is my favourite picture of one. The male whitethroat has a jingly jangly song and when he’s advertising for ladies he perches on top of a bush and flies repeatedly in a jerky motion straight up and then flutters back down to the same spot.

And while I was busy photographing the warblers I was being serenaded night after night by this chap:

A tad incongruous in a post about warblers, I grant you, but he was there all the time and his songwas magnificent! As with the chiffchaff there are several other birds calling too, but the thrush is easily distinguishable from the noise. This is the first time I’ve posted a link to my own (amateurish!) sound recording, but I think it’s OK. Let me know what you think.

The chiffchaff and the willow warbler

Posted on May 12, 2012 | 17 comments

The chiffchaff and the willow warbler both members of the warbler or ‘Sylviidae‘ family. There are 63 members of the Sylviidae of which 14 species breed in the UK. They’re very similar to look at and can be pretty tricky to tell apart. Last week in my local meadow I came across both species in photographable locations so I thought I’d try to show the differences. Both species are summer migrants to the UK having overwintered in Africa, the chiffchaff goes to the Mediterranean and some head south of the Sahara, and the willow warblers all go down to tropical sub-Saharan Africa.

This publication from Birdlife International tells us that the global population of willow warblers is estimated to be between 300 million and 1.2 billion individuals, and a fact that blew my socks off was that the northern Siberian population overwinters in southern Africa, which is a journey of over 7000 miles or 11000 km… and back! And they’re only 19cm long and weigh 10g, so they may be tiny, but they’re incredibly tough. The chiffchaff is also a scarce winter visitor to the UK.

The willow warbler has longer primaries and the light stripe over the eye, the ‘supercilium‘ is brighter and more pronounced than that of the chiffchaff, and the ear coverts of the willow warbler (the patch under the eye) are a pale olive colour. The other visual diagnostic feature which is probably easiest to see at a glance is the leg colour, the willow warbler has pinkish brown legs whilst those of the chiffchaff are much darker, almost black.

In the absence of a clear sighting the easiest way to differentiate between these two species is by their song: click here to hear the chiffchaff song, and here for the willow warbler song.

The conservation status of the chiffchaff is green and in 2000 there were around three quarters of a million territories in the UK, but the willow warbler is amber due to a decline in the breeding population, but despite that there were still two milion territories in 2000.

Returning songbirds

Posted on May 10, 2012 | 22 comments

There’s a particular spot in my local meadow where there are some large clumps of brambles which are home to numerous species of bird including songthrush, blackbird, linnet and house sparrow. And in the summer chiffchaff, willow warbler, blackcap and common whitethroat are all there too. Chiffchaff have been here for a couple of months now, and willow warbler almost as long but I hadn’t yet seen a whitethroat, so I set off last Monday in the hope of seeing the first one of the year.

There were many species of songbird in the meadow including the robin (Erithacus rubecula: Dansk: rødhals) and the house sparrow (Passer domesticus, Dansk: gråspurv) and the air was alive with the song of all these species.

Robin and house sparrow are resident species in the meadow and I see them all year round there, but not the chiffchaff:

The chiffchaff (Phylloscopus collybita Dansk: gransanger), which is a warbler, and willow warbler (Phylloscopus trochilus, Dansk: løvsanger) can be very difficult to tell apart if only seen at a glance, but they can be distinguished by their song, of which more in the next post. This chiffchaff was one of a pair which were calling to each other and flitting around the bushes passing within a few feet of me on several occasions and seemingly unfazed by my presence.

Cock linnet

Resident in the UK is the linnet (Carduelis cannabina, Dansk: tornirisk), they disappear from the fields around Histon in the Autumn, presumably to congregate at a winter feeding ground, and they reappear in the Spring. And they have recently turned up in the meadow. Also resident, and present all year round, is the dunnock…

… and the chaffinch:

There were no whitethroat back in the meadow last Monday but as you can see there were plenty of other birds. In the last week I’ve also seen kestrel, sparrowhawk and buzzard, blackcap, green woodpecker, jay and magpie.

I recce’d the meadow again this weekend and the whitethroat are now back from wintering in Africa. They are very distinctive and both sexes are easily identified by their strikingly white throat, and the males display by singing from the top of a bramble thicket or a sapling and flit 4-5m vertically into the air and then descend to land in the same spot. They’re lovely little birds, with a very distinctive song, and I’ll hopefully have some pictures to show you in the near future.
