Glenn Ousett has reported the first fledged brood that I have heard of this spring: four downy young Pied-billed Grebes accompanied by a pair of adults at the south lagoon in Joe Brown Park. This is off Read Boulevard in New Orleans East.
This observation is also noteworthy in that it is the only urban (inside the hurricane levee) nesting site I know of for this species. They nest sparingly in wetlands elsewhere in southeast Louisiana, such as in the Bayou Sauvage National Wildlife Refuge.
Lots of other species are now into their nesting cycles, so other fledglings will not be far behind.
