March and April are the best months to see Bonaparte's Gulls in the Susquehanna Valley. Like many other birds, they're on their way north this time of year.

You may think the birds in these photos are Common Grackles, but they're actually Rusty Blackbirds, much less common members of our native blackbird family.

The third week of March is the peak of migration for Horned Grebes in the Susquehanna Valley. Horned Grebes have lots of cool nicknames, like "Water Witch."

Get ready for spring bird feeding! Migrant birds will arrive soon in our area, replacing winter birds like Dark-eyed Juncos and White-throated Sparrows.

Our local blackbirds spend most of the winter in farm fields. The flocks can number in the tens of thousands, primarily a mix of three native blackbird species.

There are only seven species of swans in the world, and two of them are native to North America. By far the most common is the Tundra Swan.
