The Reed Warbler, though entirely insectivorous, is a very tame and amusing cage-bird, and may easily be fed on raw meat chopped fine and a little hard-boiled egg; but its favourite food is flies, and of these it will eat any quantity, and woe even to the biggest bluebottle that may buzz through its cage, for the active little bird will have it in a moment, and after a few sharp snaps of the beak there is quite an end of the bluebottle.  Daddy long-legs, too, are favourite morsels, and after a little beating about disappear down the bird’s throat—­legs, wings, and all, without any difficulty.  The indigestible parts are afterwards cast up in pellets in the same manner as with Hawks.

I have never seen the nearly-allied and very similar Marsh Warbler, Acrocephalus palustris, in Guernsey, but, as it may occasionally occur, it may be as well perhaps to point out what little distinction there is between the species.  This seems to me to consist chiefly in the difference of colour, the Reed Warbler, Acrocephalus streperus, at all ages and in all states of plumage, being a warmer, redder brown than Acrocephalus palustris, which is always more or less tinged with green.  The legs in A. streperus are always darker than in A. palustris; the beak also in A. palustris seems rather broader at the base and thicker.  This bird also has a whitish streak over the eye, which seems wanting in A. streperus. These distinctions seem to me always to hold, good even in specimens which have been kept some time and have faded to what has now generally got the name of “Museum colour.”

Mr. Dresser, in his ‘Birds of Europe,’ points out another distinction which no doubt is a good one in adult birds with their quills fully grown, but fails in young birds and in adults soon after the moult, before the quills are fully grown, and also before the moult if any quills have been shed and not replaced.  This distinction is that in A. streperus the second (that is the first long quill, for the first in both species is merely rudimentary) is shorter than the fourth, and in A. palustris it is longer.

Though I think it not at all improbable that the Marsh Warbler, Acrocephalus palustris, may occur in Guernsey, I should not expect to find it so much in the wet reed-beds in the Grand Mare and at the Vale pond as amongst the lilac bushes and ornamental shrubs in the gardens, or in thick bramble bushes in hedgerows and places of that sort.

Acrocephalus schoenobaenus, Linnaeus.  French, “Bee-fin phragmite.”—­The Sedge Warbler is by no means so common as the Reed Warbler, though, like it, it is a summer visitant, and is quite as local.  I did not see any amongst the reeds which the Reed Warbler delighted in, but I saw a few amongst some thick willow hedges with thick grass and rushes growing by the side of the bank, and a small running stream in each ditch.  Though
