you will probably have the pigeon, firecrest and chaffinch easily at the Balcoes
Plain swift are common in Funchal (at least in the summer...)
-Ponta de Sao Lorenço / Caniçal is good for spectacled warbler, rock sparrow, berthelot's pipit. (Ponta do Pargo isn't good anymore)
-For migrant waterbird, the best spot are Lugar do Baixo, Funchal Harbour and Machico river mouth. At this time of year there is good chance of having an american vagrant
-seawatching : the best place are Ponta do Pargo near Funchal and Porto Moniz. The best is early morning and late afternoon / evening. You'll see plenty of Cory's shearwater, a few fea's petrel and maybe little shearwater (too late for bulwer's & zino's). Porto Monis is the best spot for migrant seabirds (better in september) but if you try you can maybe see a late great, sooty or manx shearwater and skua are possible.
-boat trip I recommand :
Day trip to the Desertas Island with Ventura do Mar (good for fea's petrel, cetacean)
Whale watching trip with Madeira wind bird (probably good for fea's petrel too and cetacean)
whale watching trip with Rota dos Cetaceos (very good for cetacean)
Whale watching trip with lobosonda (good for cetacean)
