Green Heron Nesting in Coastal Louisiana Marshes
By Molly Folkerts
The Green Heron (Butorides virescens) is an under-studied wading bird with a flexible nesting strategy, nesting colonially, solitarily, or in loose aggregations. We initiated a Green Heron banding project in 2013 at Audubonís Paul J. Rainey Wildlife Sanctuary (Vermilion Parish, Louisiana) to determine factors that drive nesting flexibility and influence nest success. We located 244 nests between May and July by boat, measured nest-tree dimensions, and banded 142 nestlings from 71 nests. We revisited a subset of nests every 1-3 weeks, and estimated nest success to be 51.1% (n=184). Of the 244 nests, 44 occurred in trees with multiple nests, whereas the remaining nests were solitary. Nest success in multi-nest trees was 48.6% (n=35), whereas nest success in solitary trees was 51.7% (n=149), suggesting sociality may not be the most important factor in predicting variation in nest success. Variation in nest success and nesting strategy may be associated with tree size, access to foraging sites, water quality metrics, and water level stability, which we will continue to examine in 2014 as we continue work at Rainey Sanctuary and possibly expand to other sites.
Molly Folkerts is from Auburn, Alabama. She graduated from Auburn University in 2012 with a B.S. in Zoology and a concentration in Conservation and Biodiversity. She is now a second year graduate student at LSU-Shreveport, working toward a Masterís in Field and Organismal Biology under the advisement of Dr. Ingold. Field work for her thesis project on Green Heron nesting began in summer of 2013 and will continue through this summer. After graduating from LSUS, she plans to pursue a career in field biology and conservation.
Notice: The Bird Study Group needs volunteers to take care of refreshments for the BSG meetings on April 8, May 13, or June 10. March is already scheduled. Thanks. If you need more information, call Larry or Mac using the contact info below.
The meeting will be held in the LSUS Science
Lecture Auditorium. Refreshments at 6:00 p.m. Meeting will start at 6:30. Come
at 6 to chat with other birders!
The Bird Study Group is a non-profit membership-based organization devoted to the observation, study, and enjoyment of birds. The BSG is open to anyone with an interest in any aspect of birdwatching, study, or conservation.
