The Audubon Observer, March 2020


March 2020 Observer banner - Beautiful Crosby Sanctuary



Urgent request from Audubon Florida's Northeast Florida Policy Associate Chris Farrell:

Royal Tern with chick by Carol Bailey-White"Last year we had great shorebird nesting success at Little Talbot Island. We need many volunteers to help prepare the site for this upcoming nesting season by "posting" the area to reduce human disturbance. Requires the ability to walk and work on loose beach sand, plus perform some activities including relatively light physical activity, carrying PVC poles, and using posthole diggers.

This event will take place during the day on March 4, 2020 at Little Talbot Island State Park. Additional dates for this volunteer opportunity include March 16th, March 18th, and March 19th."

Please contact Chris Farrell at for more info and to RSVP.


This month we’re beginning an occasional series featuring bird species of special interest in Florida. Our Spotlight Species this month is the Burrowing Owl (Athene cunicularia).

Burrowing Owl by Carol Bailey-WhiteBurrowing Owls are unique among owls of North America because they nest in burrows in the ground, often ones they’ve dug themselves, although they may also occupy burrows made by other species like ground squirrels or gopher tortoises. They are fairly small at 8-9” tall, with long legs and a short tail. They have rounded heads (no ear tufts like some other owl species), big yellow eyes, white eyebrows, sandy brown feathers with lots of white speckling, and lighter coloring underneath.

They prefer open areas with sparse vegetation such as pastures or fields and are usually seen on the ground or perched on low posts near their burrows. Unlike many owls, they are often active during the day, but prefer to hunt for prey in the early morning or late evening. Insects, small rodents, and amphibians make up most of their diet. Burrowing Owl pairs are usually monogamous and typically produce one clutch of eggs each year, with an average of 3-4 offspring successfully fledged. The typical breeding season for the Florida Burrowing Owl is February 15 to July 10, though owls can breed earlier or later.

Florida Burrowing Owl distribution map FWCBurrowing Owls are year-round residents in the southwestern United States, central and south Florida and the Bahamas, and some populations migrate between Mexico and the western US. In Florida, Burrowing Owls are concentrated in central and southern parts of the state, but small pockets of Burrowing Owls have historically been recorded in the Panhandle as well as right here in northeast Florida. According to, the last recorded sighting of Burrowing Owls in our area was near Imeson Road in north Jacksonville on April 9, 1995, so they haven’t been seen in northeast Florida for many years.

Burrowing Owl populations have declined significantly in the last century. It’s difficult to get an exact figure, but population decline estimates of 25-50% have been noted. Probable causes contributing to the decline include displacement due to development and commercial agriculture, predation by domestic animals, harrassment by humans, and vehicle strikes. As a result, Burrowing Owls are considered by the U.S. Fish and Wildlife Service to be a Bird of Conservation Concern at the national level. In Florida, the Burrowing Owl is classified as State Threatened by the Florida Fish and Wildlife Conservation Commission. This means that taking, possessing, or selling burrowing owls, their nests (i.e., burrows), or eggs is prohibited without a permit.

Burrowing Owl by Carol Bailey-WhiteBut some Florida communities hosting Burrowing Owl populations have stepped up conservation efforts to save this iconic species. The city of Marco Island recently passed a resolution to pay residents $250 to start an owl burrow in their front yard. Since most Burrowing Owl colonies in the community are currently found in vacant lots, conservationists are concerned that lot owners may get permits to develop their land, thereby displacing the owls, so the initiative is aimed at providing more habitat options for these beautiful birds. Marco Island and Cape Coral, about 45 miles north of Marco Island, host the two largest Burrowing Owl populations in the state.

You probably won’t see any Burrowing Owls here in northeast Florida, but if you are in the southwest part of the state, you may want to consider a visit to Cape Coral or Marco Island to see these cool little owls. Check out Cape Coral's "Burrowing Owl Rules of Engagement" before you go!

To help you create bird friendly habitat in your landscape, we are sharing a native plant every month that is beneficial to birds and pollinators.

This month's plant is:

Passionflower Vine (Passiflora Incarnata)

Passion Flower by Carol Bailey-WhiteThis vine has a native range from Texas to Virginia and south through Florida. It is a high climbing aggressively growing vine with beautiful, showy flowers pollinated by bumblebees and carpenter bees. It is the larval host plant for the following butterflies: Zebra Longwing, Gulf Fritillary, Julia, Varigated Fritillary; also the Plebian Sphinx Moth

The Cherokee gave this plant the name “Ocoee” which translates to Apricot Place and is the name source for the Ocoee River and the town of Ocoee, Florida. The fruit of the Passionflower vine is also called Maypop because the hollow fruits start ripening in May and can pop loudly when crushed; they taste of apricots, hence the name.

It will grow in thickets, near riverbeds, unmowed pastures, roadsides, and thrives in full sunlight. It is the perfect vine to use to cover an ugly or old fence but if you wish, it is also happy in a large pot with well-drained soil.

It will attract Cardinals, Grosbeaks, Sparrows, Chickadees, Thrashers, Finches, Orioles, Mockingbirds, and Titmice.

Third in our series from board member Carolyn Antman on how you can help birds and other wildlife by using less plastic in your daily life.

"Let’s talk about plastic food bags and plastic wrap. How many sandwiches, leftover produce and other food do you put in a plastic bag? How much do you freeze in a freezer bag? How many times have you covered a bowl with plastic wrap? All of this is single-use plastic that just goes out into the environment when discarded.

I have found that using the miscellaneous plastic and glass containers that food comes in preserves food much better and longer than plastic storage bags, even in the freezer. Although I try not to buy too many of these, at least I make use of the plastic containers I have again and again.

When I buy meat (never! in Styrofoam) from the butcher, I have them wrap the Silicone food storage bagmaximum quantity in paper then I divide it at home, freezing serving sizes in reused plastic containers. Reusable silicone food storage bags like those at left are also a good option. Made of food-grade silicone, they can be washed in the dishwasher and used over and over to store meat, produce, and many other kinds of foods.

When I use a bowl that doesn’t have its own top, I cover it with an appropriate Silicone bowl coverssized plate before putting it in the refrigerator. This works most of the time and I haven’t had to buy plastic wrap in ages. Another option is silicone bowl covers like those at right; they are washable and reusable, and are readily available online and from many retailers.

Sandwiches should be carried in reusable containers. Children and spouses can be taught to bring these containers home for washing. Sandwiches don’t get squished this way either!

As always, demand creates supply. The less we use, the less is produced. Please try some of these tips and tell your friends. Share your successes on our Facebook page!"
