Duval Audubon Fieldtrip and Workday

Crosby Sanctuary: Fall Migration #1
Sunday, September 28 2008, 8:00am - 12:00pm

Seasonal Progression Series Trip #1

This series of fieldtrips is designed for birders looking to spend a few hours close to home on a citizen science and "low-carbon", local fieldtrip. Each field trip date includes a 2 hour field trip followed by a 2 hour work session to maintain native landscaping and nest boxes. Participation in work sessions is optional, but fun!

The Crosby Sanctuary is a "Hotspot" on eBird.com, with bird observation data going back to 1984. We have recorded over 80 different bird species from Crosby. We could use your help to expand our species list!

Crosby Sanctuary eBird Hotspot

Crosby Sanctuary is listed as a hotspot on eBird. There are over eighty species of birds recorded from Crosby. Please go to eBird and look up Crosby Sanctuary as a hotspot by clicking on "eBird " in the Links section of this blog. You will have to register yourself on eBird to gain access, but it's well worth the trouble. The beauty of eBird is that it lets you look at this information (data) in various ways. For instance, you can see when the first time a bird species was observed, the last time observed, and the high count (most of each individual species seen at one time) by location, hotspot, or region. It's a great way to record your bird observations, keep track of your favorite spot, and prepare for a birding trip to any of the listed hotspots. Many famous birding spots are listed hotspots and kept up to date with observations!

Clay County Ditch Work





Clay County Public Works has decided it's time once again to clean out the ditch running along the entrance to the sanctuary. They made a mess of things for a while and are still not done. We had to file a complaint with the county for their sloppy work. Hopefully, all can be resolved in a manner beneficial to both parties. They have agreed to replant the banks and keep the ditch clean of invasive exotic plants, with a little help from Audubon volunteers.

The ditch up the hill from the sanctuary actually contains a seepage spring that constantly flows crystal clear water. This ditch also drains a good sized portion of the neighborhood nearby. As such, it has been lined with concrete in the past and recently re-lined for stabilization. The county really did a sloppy job as evidenced by the pictures.

This entire ditch run would be a great stream restoration project. A functioning stream/natural ditch would slow the water down and help treat it on the way down to the sanctuary swamp. Anyone interested in helping with such a project? It probably wouldn't be that hard to get grant funding. Just need the people to help organize and get it together.


Prothonotary Warblers at Crosby


Prothonotary Warblers are back as of mid May. One has been spotted in the swamp and the nest box appears active as of May 25. These beautiful yellow birds with blue wings are as pleasant to see as their sweet song is to hear! They are unfortunately listed as a declining species throughout their range of SE US and Central/South America. We are lucky to have them at Crosby!

2nd Annual First Coast Great Air Potato Roundup



The 2nd Annual First Coast Great Air Potato Roundup on March 1, 2008, was a huge success! We collected two and a half large trash bags of potatoes (approximately 300 pounds). Thank you to Barbara Beyerl, Andrew Thornton, Pat Anderson, Larry, Nikki and Taryn Fenwick, Lenore McCullough, Gerry Murphy, and John Mikl0s. Everyone had great fun searching out air potatoes of all shapes and sizes. It was kind of like an Easter egg hunt, only all the eggs were the same color! The largest potato of all roundup sites was found by Andrew Thornton and Barbara Beyerl. It measured 16.5 inches in circumference! Andrew generously let Barbara claim the grand prize of a guided kayak trip for two for half a day from Kayak Amelia.

See you there next year!

Feb. 2 -- Fieldtrip/Workday Report



Our Fieldtrip was a huge success! We had 11 Duval Audubon members out on a beautiful, cool February morning for a bird walk and work session. A big thanks go out to the following members for their help: Patrica Knowles, Duffy Kopriva, Karen Barnum, Melinda Eckert, Rachael Sulkers, Gerald Sim, Pat Anderson, John Miklos, Gerry and Cheryl Murphy! Special thanks to Gerry Murphy, John Miklos, Rachael Sulkers and Gerald Sim for their help installing a Wood Duck nest box (see picture)! Extra special thanks to Pat Anderson, Duffy Kopriva, Cheryl Murphy and Trisha Knowles for pulling a giant bag of weeds from the native plant bed!

The group spotted 25 bird species including such notables as Great Blue Heron, Red-shouldered Hawk, Pileated Woodpecker, Northern Flicker, Eastern Phoebe, American Crow, and Black-and-white Warbler. Other evidence of wildlife included white-tailed deer tracks, wild hog tracks, river otter scat and uneaten bowfin skull. The swamp was well inundated with water, which was flowing slowly to the east.
