Notes for editors. 1  The National Infrastructure Plan has been developed by Infrastructure UK and represents the UKâs first ever infrastructure plan for the UK. 2  The Chancellor confirmed, as part of the June 2010 Budget, the establishment of Infrastructure UK (IUK), as a division of HM Treasury.
A baby cardinal is ready to fly 10-11 days after hatching. 2-4 young are usually hatched at a time. When fully grown, their body length will reach about 21 cm.
The female northern cardinal builds the nest and incubates the eggs. When the chicks hatch they have no feathers or down, so the female broods them to protect them and keep them warm for at least 2 days. Both parents feed the chicks a diet of insects.
