Missouri marshes are a great place to find a number of bird species in late summer and early fall. This Common Yellowthroat, a species of wood warbler, was photographed this August at Riverlands Migratory Bird Sanctuary. This guy was packing Mayfly in his beak two or three at a time to bring back to the hungry chicks in the nest.
A visitor to Missouri’s marshes during migration, the Caspian Tern will always take advantage of the easy fishing that can be found at Riverlands and surrounding wildlife refuges along our great rivers.
Anyone who spent any amount of time in the marsh will know the Great Blue Heron. This giant, yet leery bird is a common site, hunting for fish or any other vertebrate it can catch.
A very common nester in Missouri marshes and fields, the Dickcissel advertises its presence with its incessant song.
So attached to the Marsh, they named the bird after it. The Marsh Wren sings its musical song throughout the day and is quite territorial.

Excellent Photos. You must have been quick with your camera to get these birds.
Thank you, Shawn! Lots of patience and luck!
