April brings warmer weather to Chiang Dao. Resident birds continue to use the garden, while many species become more active as the breeding season approaches.
Example birds: Crimson Sunbird, Olive-backed Sunbird, Oriental Magpie-Robin, Red-whiskered Bulbul, Black-crested Bulbul, Common Tailorbird, White-rumped Shama, Greater Racket-tailed Drongo.
The early morning is usually the most comfortable time to explore the garden and listen to bird calls.
