- As it was believed to be rare, it was formerly listed as Vulnerable by the IUCN. It is now known to be locally common in the Indian states of Andhra Pradesh ,kerala and Tamil Nadu

ENERGY EFFICIENCY DRIVES SEASONAL MOUNTAIN BIRD MIGRATION [ecology]
- Birds move up and down mountains primarily for food, and not to track temperature as previously thought.
- Migration is the movement of birds across long distances, from temperate to tropical regions during winters, and vice versa. The birds move to areas with more or increasing resources and to stay within the climate niche to which they are adapted.
CARBON FIBRE IN MISSILES [technology]
Carbon fibre is used in missiles to create high-strength, lightweight structures that extend range, allow for heavier payloads, and withstand high temperatures. Used extensively in solid-fuel rocket motor casings, nose cones, and airframes, this material enables improved acceleration, high-G maneuvers, and better thermal stability compared to metals.
