A nesting creature is usually a person who creates a home for themselves, usually in their room. Often this is down by retreating to their room, away from social situations whereby they eat all of their meals and watch reality tv in their room, or their "nest".
James has become a nesting creature. With multiple pizza boxes on the floor and his reality tv on his laptop, his nest is in strong development.
To put the puck in the net..... more so up in the top.
Reason for calling itbird nesting is because the nest of a bird is up in a tree, and the puck is the bird going back to the nest :P
