Spicebush (Lindera benzoin).
Great Blue Heron (Ardea herodius) perched far across the marsh.
A second Great Blue Heron, not far away from the first one. Both flew off.

Called polynoses where I grew up, but with many other common names like whirligigs, whirlibirds, and helicopters...
...the technical term for this winged seed type is a samara (https://en.wikipedia.org/wiki/Samara_(fruit)). Not only can they be thrown up in the air to watch them spiral down; they can be split at the seed end and pinched onto your nose.
An afternoon walk west of River Road to see Trailing Arbutus (Epigaea repens) in bloom.
April 21st. Light rain. A lone male Wood Duck (Aix sponsa) far out in the marsh.
