Red-necked Grebe second brood chick riding on back of first brood juvenile

 Mike Leahy

Red-necked grebes have nested in Kirkland Lake in 2020 and 2021. This year, an unusual second brood was attempted - a new nest site was established near the first nest and three eggs were observed in the new nest. One young has hatched from the new nest and has been seen August 9th riding on the back of a juvenile from the first brood. The ride lasted for at least 20 minutes and the ridee seemed to be ok with the young sibling passenger.

WOW! Now that's really cool! That'd definitely be worth a short write-up for publication in Ontario Birds. 

Reading the Birds of the World account (Stout and Nuechterlein 2020), it says, "Second brood rarely is attempted if first is successful; second brood is initiated while young from first brood are still dependent (Wobus 1964, Riske 1976, De Smet 1983). One record of successful second brood in North America (Mink and Gibson 1976)."
