The ospreys have declined in numbers over here for unknown reasons. Some ten years ago we had a pair down at the little lake nearby. They werebreeding every year, once I saw them with three fledging youngsters at the same time. Haven't seen any in seven or eight years.
I often see ospreys posted here. Are they still common in America?
And what happened to your 500/4.5? Still waiting for spares?
