i actually haven't seen a baby pigeon thinking about it now! you see all the other baby birds taking flying lessons from their mums and catching worms in the garden but not pigeons! maybe they're born instantly old looking
but i do know that certain bumble bees live in little holes in the ground you can make little nests for them with a small tube pipe and some long dog hair which they will live in for up to two years i think!
when pigeons leave the nest they are pretty much identical to adults.
Most moths are nectar feeders. Some feed on fruit, sap or rotting matter. Some however only feed in the caterpillar stage- adult lifespan of adult moths (and butterflies) tends to be very short
Frogs will eat moths and also dragonflies if they can get hold of them
