The best time of the year to visit Manipur for wildlife and ecotourism is generally during the dry season (October-May). The weather is pleasant during this time, with clear skies and cool temperatures. The forests are also less dense, making it easier to spot wildlife.

During the monsoon season (June-September), the weather is hot and humid, and the forests are dense with vegetation. This can make it difficult to spot wildlife, and the roads can be impassable in some areas.

Throughout the year, depending on the activity, there are opportunities for wildlife viewing and ecotourism in Manipur. However, the best time to visit for these activities is during the dry season.

Specific times for certain species, such as the brow-antlered deer, are also important to consider when planning a trip to Manipur for wildlife viewing. The brow-antlered deer is a shy and elusive species that is only found in a few areas of Manipur. The best time to see this species is during the winter months, when they are more active.

In conclusion, the best time to visit Manipur for wildlife and ecotourism is generally during the dry season (October-May). However, there are opportunities for wildlife viewing and ecotourism throughout the year, depending on the activity and the species of interest.
