Purple martins are returning from South America. The first "scouts" have been spotted in Michigan. What to know.

The largest bird in North America, the California condor most often nests in natural cavities along cliffs, including caves. However, they may also nest in large trees, such as the coast redwood.

Since hatching, Jackie and Shadow’s three eagle chicks have spent time eating, tumbling, thriving and ‘bonking’ in the family nest near Big Bear Lake.

Live streams are available from Traverse City, West Michigan, and Ann Arbor among other locations. Eagle cams offer a glimpse into the lives of bald eagles, from nesting to raising their young.
