Sighting a certain species of birds and blooming of wildflowers are telltale signs of the forthcoming monsoon season
If you happen to sight this migratory bird, Pied Crested Cuckoo (locally known as chatak), then the rain is not far behind.
Amaryllis is a species of garden flower which blooms before monsoon, and is considered harbinger of rain.
Another indicator of rain is Trombidiidae, also known as red velvet mites or rain bugs. These are eight-legged arthropods found in plant litter and are known for their bright red color.
Rain lilies, found in most Goan gardens, also bloom just before the beginning of the monsoon.
Fireflies around the edges of the forests in summer are also indicators of the forthcoming rainy season.
Bullfrogs come out in large numbers after the first pre-monsoon showers. Their loud croaking, which is meant to attract females for mating, is an indication of the approaching monsoon season.
