Recognising Common Woodland Birds on Your Walk

You Already Have the Best Equipment

Most people who struggle to identify woodland birds think the problem is kit. It isn't. Around Reading, the woods at Sulham, Crowsley Park, Mapledurham and along the Kennet valley are full of birds that will happily show themselves if you slow down and pay attention. The two tools that matter most are your ears and your patience, and you can't buy either.

Birdwatchers talk about jizz — the overall impression a bird gives through its size, shape, posture and movement. It is far more useful than plumage detail in a wood at dawn. Learn the jizz of five common species and you will identify most of what you meet on a Berkshire walk without ever lifting binoculars.

A few general rules before we start. Walk quietly, stop often, and stand still at the edge of a clearing rather than pushing into it. Birds detect movement long before they hear you. Overcast, still mornings in late March and April are the best of all, because the dawn chorus carries further in damp air.

The Robin: The Bird That Finds You

Robins are the woodland beginner's greatest ally because they come to you. On any walk with a bit of undergrowth and a few low branches, a robin will often appear within a minute or two of you pausing, perching close and watching to see whether you disturb insects.

• Song: thin, high, wistful notes that seem to trail off uncertainly before starting again. It is one of the few songs you will hear in deep winter, when most birds stay silent.
• Call: a sharp, ticking tic-tic-tic, often the first sign that you have walked too close to a territory.
• Behaviour: drops to the ground, hops, pauses with a cocked head, then flits back up to a low perch. Restless and curious rather than shy.
• Silhouette: small, round, upright and long-legged for its size — almost a tiny thrush on stilts.

Blue Tits, Great Tits and the Winter Flock

If you hear a light, high tsi-tsi-tsi overhead and then a scatter of tiny birds moving through the canopy in the same direction, you have met a mixed feeding flock. In winter these loose gangs move through Reading's woods together, often with great tits, coal tits, goldcrests and a treecreeper or two tagging along.

Blue tits are the ones that hang upside down at the tips of thin twigs, acrobatic and quick. Their song is a thin, hurried trill that rises and falls. Great tits are bigger and bolder, with a black cap and a broad black stripe down the chest. Their song is one of the easiest in Britain to remember: a clear, ringing two-note phrase, often written as "teacher, teacher". Once you hear it, you will not mistake it again.

The trick with flocks is not to chase them. Stand still, let them pass around you, and look for the busiest twigs at eye level and just above.

The Nuthatch: The Upside-Down Bird

Nuthatches are common in the mature beech and oak woods around Reading and along the Chilterns edge, but they are easy to overlook because they work high up and move with purpose. The giveaway is posture: a nuthatch walks head-first down a trunk. Treecreepers, which look superficially similar, only ever go upwards and always start low.

• Call: a repeated, clipped chwit-chwit that sounds slightly impatient, like a small stone being tapped.
• Look: blue-grey above, warm buff below, a black stripe running through the eye like a mask.
• Behaviour: hammers seeds into bark crevices to open them, which is where the name comes from. It also caches food in autumn and returns to it in winter, so a bird working a regular route along a trunk is very likely a nuthatch.

Woodpeckers: Listen Before You Look

You will hear woodpeckers long before you see them. The great spotted woodpecker's drumming is not feeding — it is advertisement, a rapid mechanical roll lasting barely a second, often delivered from a dead branch high in a beech or ash. It sounds drier and faster than anything else in the wood.

Its call is a sharp, explosive kek, sometimes repeated as the bird flies in a bounding, undulating flight between trees. Look for a black and white bird with a bold white shoulder patch; males also have a small red patch on the back of the head.

The green woodpecker is a different creature altogether. Its call is a laughing, descending yaffle that carries right across a field. Unusually for a woodpecker, it spends much of its time feeding on the ground, hunting ants on short grass at woodland edges and along rides. If you see a large greenish bird bounding away low over a meadow near Mapledurham or the Sulham estate, that is almost certainly it.

Making It Work on a Berkshire Walk

You do not need to learn everything at once. Pick three species and commit to them for a season.

• Learn one call per bird, not all of them. The robin's winter song, the great tit's "teacher, teacher", the nuthatch's chwit and the great spotted's kek will cover most encounters.
• Stop at edges. Woodland rides, hedgerow boundaries and the strip where trees meet open ground hold far more birds than deep shade.
• Give a territory five minutes. Play the same patch repeatedly and you will start to recognise individual birds and their routes.
• Note what the bird is doing, not just what it looks like. Upside down means nuthatch. Head-up on a trunk means treecreeper. Ground-feeding in a meadow, laughing, means green woodpecker.

Do this for a few weeks and the wood stops being a green blur. It becomes a place with familiar voices in it, and every walk from the Kennet to the Chilterns gets considerably richer for it.
