You will have but little trouble in recognizing this brilliant and talkative little Warbler, which comes to us both as a summer resident and as a migrant. In late April I am always sure to see its green and gold feathers among the hemlocks on the east side of the garden, while it continually utters its anxious and persuasive notes, to which I eagerly respond. It repeats a little phrase that separates it from the indistinct songs of so many of its tribe: "Will you co-ome, will you co-ome, will you?" it says, giving a particularly emphatic pause on the last two syllables.

It has never nested in the garden, and only comes to it before the breeding and after the moulting season.
