Ducklings take leap of faith on UCD campus
6 May 2014
On my way through University College Dublin campus I came across a Mother duck with her ducklings and they brightened up my day. Make sure you watch this until the end!
Mandarin duck and wood duck ducklings are known for jumping out of tree nests shortly after hatching. I did not know yet about mallard ducklings like in this video.
