Every bird in John Clare's poem is trying to protect a nest, and nearly every one is doing it differently. The firetail chatters at anyone who passes, which tells the boys exactly where to look. The yellowhammer goes quiet and slips away. The nightingale and the pewit make a fuss until their nest is discovered, then fall silent. The wren and the robin make a show of noise and leave. The central idea is that alarm is a kind of language, and in this poem the wrong listeners can read it. The birds' signals become clues, and the "noisy boys" are the ones who understand them.
The poem opens with that idea: "The firetail tells the boys when nests are nigh." The verb "tells" makes the bird a talkative informer, giving away secrets without meaning to. Her flaw is indiscriminate panic, because she tweets and flies "from every passer-bye." She cannot tell a harmless walker from a nest-robber, so she warns off nobody. The yellowhammer seems to have the better strategy. Clare sets "silence" against "noisy" in a single line: "But flies in silence from the noisy boys." Yet the next couplet undercuts any sense that silence wins. "The boys will come and take them every day, / And still she lays as none were ta'en away." The grammar is quietly stubborn, and the line carries a good deal of pathos. The bird keeps laying as if nothing had happened, and the poem refuses to comment on it.
In the longer second movement, Clare shifts from simple contrasts to something more like theatre. The pewit (the lapwing) "hollos 'chewrit' as she flies / And flops about the shepherd where he lies." The word "flops" suggests a bird pretending to be clumsy or hurt, drawing attention to herself and away from the nest. When the nest is found, she "stops her song / And cocks [her] coppled crown and runs along." The change from loud to hushed, and the crest raised with a kind of offhand dignity, makes her seem almost human, a performer who has dropped the act. The square brackets around "her" look like an editor's repair to the text, which may be a sign that the poem survives in a rough, unfinished state. That fits its jotted, observed quality.
The sound words carry much of the charm. The nightingale is "tweeting-churring," a compound that mimics the song's two textures, and the pewit's cry is spelled out phonetically as "chewrit." Clare uses "hollos" for the pewit and again for the robin, so these small birds are made to sound like farm-workers shouting across a field. The robin's cry, "tut," is a tiny click of disapproval, like a person tutting before walking off. The wrens "cock their tails and chitter loud and play," and the word "play" is nicely ambiguous. Is it real play, or a performance of carefree behaviour to hide anxiety? The poem leaves the question open.
The form is plain and quick. It is written in rhyming couplets, mostly in lines of ten syllables with a loose iambic beat, and nearly every line is a self-contained observation. The rhymes (nigh / passer-bye, noise / boys, round / found) are simple and satisfying, and they snap each bird's behaviour shut like a lid. The second section lengthens to ten lines, and then the poem ends abruptly on the robin, with no summing-up and no moral. The effect is like a walk along a hedgerow where each bird appears, does its piece, and vanishes.
That refusal to sermonise is what makes the poem significant. Clare writes as a close watcher of birds, with rural words like "pewit," "coppled" and "ta'en" rather than polished literary vocabulary, and he treats each species as an individual with its own temperament and tactics. The nest-robbing boys are not condemned in so many words, yet "still she lays" is enough to make a reader feel the loss. The poem's strength is that it sees the situation from both sides, noticing how the hunters read the birds and how the birds cope with being hunted.
