Prothonotary warbler singing

Prothonotary warbler. I took this shot on May 2020 during the weeks of the bird migration. This is one of the most beautiful birds I have ever saw and sadly it seems that it will be harder to find this little guys around as the population is decreasing over the years. The only numbers I could find are from 2005 and it estimates 28 to 35 individuals. I really hope it increases.
