Hello,
We have a pair of swans in our local park who are raising four cygnets, hatched in the second week of May this year (2021) and doing very well, They are nearly as big as the adults (3rd week of July).
The female has recently started moulting but along with that is showing some odd behaviour. She’s been moving floating twigs, just picking them up and dropping them behind her. She also does this on land but with weeds growing from the side of the pond – just pulling them out and dropping them behind her then walking on. I wondered if she was trying to demonstrate nest building to the cygnets but if so, they weren’t taking any notice – too busy eating the food people bring them – peas/corn/swan pellets/calci worms/oats etc. (thankfully most people don’t bring bread). She seems possibly hormonal as she started grabbing food from the cob that we had given him (dandelion leaves). Just wondering why she’d be doing this now as it’s not nest-building time.
