Birding at Zapata, Playa Larga
The best time of day for birding is the morning. Don't go too early, otherwise mosquito might eat you up.
The best months are November until April in the dry season. Rainy season from July until October is not recommended, as areas can be flooded. Shoulder season May and June, showers may occur but easier to find a casa without booking in advance. July and August are the Cuban school holiday.
Birding at National Park Zapata is outstanding. We did this guided tour twice with different guides at different months. A car is necessary to go to this three different places. Our second guide Yeniel was one of the best we ever had. We got him recommended from Hostel Mayito, best accommodation and delicious fresh fish. The first part of the tour leads to a swamp area which is flooded in the rainy season. The second to a dry forest and a blue lake where we took a bath. This path is called "Sendero Enigma de las Rocas". The last part leads to a bat cave. These bats are the only ones which feed on leaves. It's a swamp area and lagoon the reason for many mosquito at dusk; insect repellent is necessary. Luckily we always carry a mosquito net in our luggage.
Special tip for spotting hummingbirds: Go in February. There is a garden with a large blooming tree 5 km on the street 116 (11), in a village before Playa Larga.
