The late winter/early spring wildflowers have already started blooming at the sanctuary. It's amazing to see some of them this early, but not a big surprise due to our warm winter this year. Here are a few pictures taken today (Feb 2, 2013):
Redbud (Circius canadensis)
Red Maple (Acer rubrum)
Violet (Viola sororia)
Carolina Jasmine (Gelsium sempervirens)
Grass-leaf sagittaria (Sagittaria graminea var. chapmanii)
Carolina cherry laurel (Prunus caroliniana)
Spiderwort (Tradescantia ohiensis)

Thanks all the volunteers who helped gather air potatoes and pick up trash. We only found about 15 potatoes! This means that we are finally on top of this tenacious exotic plant after 6 years of spring roundups and about 3 years of summer herbicide applications on the vines!!!! Persistence pays off.
Ed Rutherford deserves much of the credit for spraying vines and picking potatoes on a regular basis. Ed we at Duval Audubon really appreciate you efforts. Thanks for all your help at Crosby.

6th Annual First Coast Air Potato Round-up on Saturday March 3rd from 9:00 a.m. – 12:00 p.m.
Please join us for this annual event to help control invasive air potato vines and maintain the sanctuary.
Lunch and drinks will be provided for all volunteers!
Volunteers are needed to help rid our natural areas of Air Potato vine and other invasive plants. Invasive species smother our native plants and are one of the greatest ecological threats to natural communities in Florida.
Gather all your friends and family & participate in this fun event! No registration necessary unless you’re bringing a large group. Just head over to one of the many work sites! Prizes awarded for the two largest potatoes found!

Numerous "first of season" Yellow-rumped Warblers were observed by Pete Johnson at Crosby on October 26, 2011! We were out there for our monthly work session from 8 a.m. to 11 a.m. It had been raining early in the morning, so nobody else showed up except for Ed Rutherford and myself.
As usually happens, when the weather is bad the birding is good. I observed about 30 different species of birds in a couple hours, then entered species/numbers count data in eBird.org when I got home!

A list of the species of birds observed at Crosby is available from the Links section at right of this blog page, or from DAS website. There are now 101 resident and migratory bird species known to occur at Crosby. The real number of bird species is probably considerably higher than this.
Bird records from Crosby are recorded on www.eBird.org, where Crosby Sanctuary listed as a hotspot.
Bird surveys are conducted on a regular basis on the first Saturday of each month starting at 8 a.m.
Volunteers are welcome! Contact email@example.com for more info.
