Every Spring the same mother duck visits our backyard. Sometimes she lays eggs and sometimes they hatch.
The last couple times we have left the ducklings under the care of the mother duck. However, there are plenty of crows in our neighbourhood and so the number of ducklings diminishes.
Now I'm not sure whether they are usually all eaten or whether some of them make it. We haven't seen them fly away before. Last time they hatched they were gone all of a sudden - including the mother and this was only a few days after them hatching. So we are not sure whether they usually live.
Should I leave them be (without human interference as nature intended) or should I call DEC, NativeARC or the local rangers?
