Birdsong is perhaps a bit less intense in May than it was in April, because many birds have moved from trying to attract a mate to raising young, and so have less time to sing. But you can still get lots of layers of birdsong towards dusk, particularly in suburban parks, woodland and wildlife reserves, as well as scrubby areas in the country. (On farmland the concentration of birdsong is not so intense.) In general it is a frustrating month to try and identify what birds are singing, because foliage now hides them from view.
One bird that is very prominent all month, both in sound and visually, is the blackbird, whose lovely melifluous song is sung by males perched high on trees and rooftops. They can sing at any time of day, but there seems to be a kind of "blackbird time" at about 3-4pm when they pipe up, their unhurried song conveying the impression that the day's labour is over and it is time to relax. They then dominate the soundscape on the long light evenings, particularly in villages or suburban areas, where you hear overlapping layers of blackbird song. Very occasionally towards dusk they resort to tup-tup-tupping competitions instead. Keeping them company is the song thrush, which is heard at dusk throughout the month, and usually once or twice earlier in the day.
The cascading song of the chaffinch is also common throughout the month. It lays its eggs in May so the song is less intense towards the end, but still fairly regularly heard. It is worth checking that what you think is a chaffinch is not a willow warbler, however, as their song sounds quite similar to the casual ear, though they now seem to be quite rare in the south east of England.
Chaffinches also make a metronomic tseep!... tseep!....tseep!... that can go on for ages. There are two versions of this - a rather harsh, raspy one (clip: known as a "rain call") and a softer toned one (clip). The latter can sound very much like a similarly repetitive call of the chiffchaff (clip): I have observed both birds making the call at this time of year, though it usually seems to be the chaffinch. Both can engage in duels with other birds where they swop "tseeps" for prolonged periods. The ponderous song of the chiffchaff (which sounds like its name) also continues to be heard most days throughout the month, though it is much less frequent than it was in early April, when they were newly arrived from their migrations and competing for territory.
Lots of other birds that were vociferous earlier in the spring are now piping down. Blue tits and great tits are occasionally heard in early May but have generally stopped singing entirely by the middle of the month as their young are fledge. For the rest of the month they remain in pair bonds, caring for their young, so do not even make the cheerful contact calls they make the rest of the year when feeding in groups.
Robin song is also much less common, though they can sometimes be heard singing right to the end of the month, particularly at dusk - often in short bursts as if they have no time for more developed songs. The loud trilling outbursts of wrens are heard most days but are no longer as common as they were in early April. You might hear the occasional green woodpecker laugh (it is technically known as a yaffle) or the song of the mistle thrush, which sounds distant even when it is not.
Dunnocks also quieten down and focus on raising their young in May, though they can occasionally be heard (and seen) singing right to the end of the month. (Indeed, there may even be a renewed flurry of song around this time, perhaps because these notoriously promiscuous birds are having a second go at breeding). Their squeaky supermarket trolley song sounds similar to that of the blackcap, but the latter is louder, more confident and starts with mumbling notes. Blackcaps are very vocal throughout the month, perhaps tailing off a bit at the end.
Just to make life confusing, the whitethroat, a summer visitor active throughout the month in shrubby territory and hedgerows between open fields, also has a similar song, albeit much shorter than the blackcap's and more scratchy. It has a display flight where it flies up into the air and lands again. There is also the garden warbler, whose song is like a speeded-up, perhaps even demented, version of the blackcap's but with some scratchy notes like the whitethroat. They are not the commonest of birds, remaining hidden in trees and scrub. If you catch sight of one you might mistake it for a chiffchaff, as they are quite nondescript in appearance, with a lighter belly. Despite their name they are not a garden bird.
Dunnock nests are favourite targets for the parasitic cuckoo to lay its eggs. Sadly these birds are in major decline, but you can still hear them occasionally in May (usually, it seems, a long way away). Both the New Forest and the area around Haslemere have been reported as good locations for them (and in the north west of Scotland they are apparently positively common).
Other summer visitors are more visible (though worryingly perhaps a little less common than they used to be). A cheering sight is swallows swooping overhead catching insects - or are they house martins? Both birds have white bellies and both fly pretty fast, making identification hard. Perhaps the easiest way to distinguish them is that swallows quite often fly very low - sometimes only half a metre above the ground - turning sharply and unexpectedly like a jet fighter and even dipping into ponds to drink while on the wing. They also have a long forked tail and a dark throat, if you ever get that good a look at them.
House martins, by contrast, are more sociable, nearly always appearing in chattering groups, and nearly always seen near buildings, where they nest in colonies. They tend to fly at rooftop height, in a sort of "flap flap glide" flight rather than the smooth swoop of the swallow. They have a stubbier tail and a white patch on their rumps (the bottom of their back). The two species also have distinctive calls - the house martin's being a kind of staccato rasp and the swallow sounding like a squeaky bath toy being rapidly pressed.
Often lumped together with these two, but in fact from a quite different family of birds, is the swift, which does not in fact fly that fast, and has distinctive swept-back wings and entirely dark plumage. They generally are often seen high in the sky, particularly over ancient towns with convenient church towers to nest in, but also sometimes in more rural areas, where they can sometimes come quite close to the ground in pursuit of food. At such times you may hear their screaming call. They spiral upwards into the sky at night to sleep on the wing and even mate in the air. The only time they ever land is to raise young.
Near houses you can hear the twittering of sparrows, once very common and now maybe making a bit of a comeback. Greenfinches are also almost exclusively found near habitation, where the males are easy to see as they sit on high perches making their "squeezh" of a mating call. Lone goldfinches sing from similar positions, and also twitter excitedly as they fly past in small groups, though just occasionally what you think is goldfinch song turns out to be swallows chattering as they fly overhead.
Villages and more rural suburbs are also where you hear the cooing of collared doves - "hoo-hooo hoo": look for them on chimney pots - or the "hoo-HOO-HOO-hoo-hoo" of the wood pigeon: the latter can also be heard in the countryside, and both birds sing throughout May. A bit less common and much more inconspicuous is the repeated throaty "woo" of the stock dove, more of a woodland bird.
In fields with hedgerows listen out for the quiet but penetrating song of the yellowhammer, which should start around mid May but can be heard earlier if the weather is fine. It is a rapid series of notes a little bit like a blue tit's mating call, followed by a long drawn out "eee", but the bird often leaves out the "eee". (One can get quite tense wondering if the wretched thing is going to finish the phrase or not!). As you might expect, yellowhammers have lovely bright yellow plumage on their heads and breasts, and they usually perch prominently on a bush. But they are nonetheless remarkably difficult to spot.
Over downland and arable fields larks trill invisibly overhead, and on wilder downs you can also see or hear meadow pippets, with their accelerating trill and parachuting display (that is, they fly up and then glide downwards). In coastal and downland scrub you may just hear stonechats, with their frequent "tchack" calls, and red-breasted linnets, who have a rapid twittering song a bit like that of the lark. On shingle beaches (eg the area behind the beach at Cuckmere Haven) look out for well camouflaged ringed plovers, who give their location away with a thin piping call.
In reed beds you can hear both the reed warbler (another favourite of the cuckoo) and sedge warbler in May. The latter has a scolding, chattering song and usually sings from a neighbouring bush, while the former is more regular, rhythmical and scratch and comes from the reeds themselves. If you are near Romney Marsh, however, what you think may be either of this birds singing might in fact be a marsh frog, an invasive species which unlike our native frogs has a very loud croak that can sound somewhat bird-like.
