We spent 6 nights in Praslin, did walk all round the island and also rented bikes for two days. The bikes were handy to bird in the good marshy area at Fond de l'Anse. Where the road to Zimbabwe starts we had good views of S. Black parrot but no S. Kestrel, unfortunately. We spent the last three nights in Mah Sun Resort guesthouse at Beau Vallon, again we didn't find a room in the place you suggested even though everything looked quite empty. This is another good place to stay, very nice new rooms with kitchen facility, swimmingpool and restaurant.
Bus stop and beach nearby.
The Northern part of the island, the promontory, was not very interesting at this season, no sea birds at all, as well as along the East coast south of Victoria. On the West coast, at Anse aux Poules Bleues, we saw our first ever Crab plover, a juv. The big pond at Plantation Club Hotel gave us excellent sight of two Yellow bitterns, together with Green-backed heron and Moorhen. We missed the S. Kestrel, we did check every single church on the way but saw none.
