Our celebrated migratory Reddish Egret, Ding#1, has done it again. She left the J. N. “Ding” Darling National Wildlife Refuge (NWR) on Sanibel Island, Lee County, Florida, to spend the late summer months on the Nature Coast in Dixie County, Florida, from 2 June through 17 August 2016. In 2015 she made a similar migration to the same location at the end of May, but only stayed a few weeks.

Based on her breeding-season movements relative to wading
bird nesting colonies in Lee County, we do not think this female nested in the
spring of 2016, or at least not successfully. This could be why she spent more
time on her Dixie County range in 2016. Her northbound migration was direct and
punctuated by only one over-night stop, seaward of Homosassa in Citrus County. Once at her “winter” destination, she used a
single foraging area on the coast of the Big Bend Wildlife Management Area (WMA)
in Dixie County, from which she flew five miles offshore each evening to spend
the night on a small island. This
pattern continued for 11 weeks.

On 18 August, just after midnight, Ding#1 started south by
the light of the full moon. This is the
only time we’ve ever recorded a Reddish Egret embarking on a long flight at
night. We also were interested in
offshore night locations, perhaps on a channel marker or stationary boat, where
Ding#1 rested for at least two hours. After resuming her southbound night
flight, she took one more rest just before dawn in a tree overhanging a house
in a busy subdivision in Largo, Florida.
After sunrise, Ding#1 made a bee line to Pine Island and may have fished
there for a few hours before returning to her favorite roost near the Wildlife
Drive, on the Ding Darling NWR. She
completed her at least 230 mile southbound trip in less than 24 hours,
including rest stops. Very impressive!

ARCI and our friends at Ding Darling NWR were not the only
ones glad to know that she made it back safely.
Not even a day later, photographer Jim Bennight was on the Wildlife
Drive and captured a wonderful greeting ritual between Ding#1 and her mate Ding#2.
It is worth noting that Ding#1 is the
only migratory individual among the 14 Reddish Egrets we have tracked by
satellite from the lower Florida Keys, Florida’s Big Bend, and on Ding Darling
NWR.

Ding#1 and Ding#2 continue to grace the Refuge’s Wildlife
Drive. A few non-tagged birds also have been
seen on the Refuge. We continue to track five Reddish Egrets in Lee County, plus
the single bird tagged on Big Bend WMA in Dixie County. All of the tagged birds
displayed their usual movement patterns during the red tide event that affected
Sanibel and area waters in late November. We are monitoring them closely for
any changes in behavior. You can keep up with the movements of these now-famous
