BY EDWARD VERNON HARCOURT, ESQ. SIR,-According to your request, I send you a short account of

the birds that breed in Madeira, together with a list of those that visit the island.

The birds of Madeira are less numerous than might be expected in so genial a climate, and most of them are merely varieties, where they differ from European species.
