Crow’s nests and Raven’s nests
The top and bottom photos are a Crow’s nest and in the bottom one some is taking a first flight.
The middle ones are a Raven’s nest and the Ravens weren’t even fledged yet.
Both make really messy nests
The Raven’s nest is twice the size of the Crow’s nest and the Raven babies unfledged were almost the size of the fully fledged Crows.
