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.

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 is probably because in Guernsey the Wheatear has a great partiality for laying its eggs under large slabs and boulders of granite perfectly immovable; the stones forming one of the Druids' altars in the Vale, were made use of to cover a nest when I was there. REED WARBLER. Acrocephalus streperus, Vieillot. French, "Rousserolle effarvatte," "Bec-fin des roseaux."
