A warm and (mostly) quiet morning. Overcast, and the warmth has brought down snowmelt from the mountains to the west.
Despite the snowmelt, and a high tide, the Estuary wasn't as inundated as it was on Thursday. Paths were muddy, but navigable. The fields are full of ducks--mostly mallards and wigeons. The ducks must be what are attracting eagles--I counted at least 10 this morning. Reading up eagle behaviour on the Birds of the World website, I find that in addition to their usual soft twittering, they can indeed shriek when there are territorial issues. I was startled at how loud they can be as I walked through the shrubbery near the entrance of the Estuary. I couldn't see them and didn't realise what I was hearing at first. Then I saw 6 adult eagles, not looking really friendly.
The usual flocks of ducks were less visible. I suspect they're just dispersed through the fields. There were flights of wigeons at times. The eagles were further inland, and didn't do their usual strategy of frightening waterfowl into the air.
It was actually warm by the time I ended my walk. In the next few days it's supposed to become chilly and clear, although rain is forecast for Christmas day.
