Detalhes da observação
Not sure how to manage the counts here. Most birders visiting quickly will estimate 50/60 birds. A conservative estimate of nest sites is: North side 20 South side high level 20 South side low shed 10 West/water side 5 Total 55 nest sites Has to be at least an average of two active nests per site and two birds per nest means 220 birds. Attached photo has one of the smallest nest sites and it looks like 9 birds attending.
