Mallards

You can't really see the green headed mallards, but when I opened by BirdNET app, that's what it heard.

Wikipedia: Males (drakes) have green heads, while the females (hens) have mainly brown-speckled plumage. Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes. The mallard is considered to be a species of least concern by the International Union for Conservation of Nature (IUCN), and, unlike many waterfowl, are considered an invasive species in some regions. It is a very adaptable species, being able to live and even thrive in urban areas which may have supported more localised, sensitive species of waterfowl before development.

I've seen a lot of spring flowers on social media, but these were the first I saw in the real.
