A View of Bird Rookery Swamp- Black-bellied Whistling Ducks

black Black-bellied Whistling Ducks

Bird Rookery Swamp observations
Saturday, October 24 ~ 7:10 am-1:20 pm

“Nice day with 36 species of birds and 13 species of butterflies. Top birds were a flock of 9
black Black-bellied Whistling Ducks foraging in the Pickerelweed to the east of the gravel path leading to the boardwalk. A photo with one adult and three of the juveniles in the family is attached. Also had two Pied-billed Grebes in one of the large open water areas between markers 6 & 3.

Lots of night herons were back — 15 Black crowned combinations of adult and juvenile. I didn’t see any gators the first three and a half
hours, but it was cooler then. Once the sun warmed things up, they came out. A photo of a seven-eight footer is attached; it was acting as “greeter” between the end of the boardwalk and Ida’s pond (no Ida, though).” – Dick Brewer Gator on the BRS trail

A View of Bird Rookery Swamp- Water on the Trails

Black and White Warbler
Bird Rookery Swamp observations
Saturday, September 5 ~ 7:15 am–1:15 pm
“Below are my observations from today at Bird Rookery Swamp (BRS). Not a bad day for birding, especially with more Barn Swallows over the meadow opposite the start of the boardwalk and a small “flock” of Eastern Kingbirds between markers 6 & 3. Attached is a photo of a Black-and-white Warbler that was prying little insects from bark crevices in a cypress near Ida’s Pond; it has one in its bill. Ida wasn’t visible while either going out or coming back. Several pairs of hikers armed with cameras were on the trails plus two bicyclers; the bikers turned back a little past marker 3 toward marker 6 when the mud got slippery and the water was flowing over the trail. Other than that, a nice day!

A View of Bird Rookery Swamp- Belted Kingfishers are Back

Belted Kingfisher
Bird Rookery Swamp observations
Saturday, August 22 ~ 7:15 am-12:35 pm
“It was a good day with 33 species of birds. Nice ones were a dozen Barn Swallows flying over the gravel path on my way out, and a pair of Prothonotary Warblers in the cypress/maples between markers 6 & 3 and a pair of Belted Kingfishers around the parking lot pond. Also had a Marsh Rabbit scurry across the tram.

Attached are some photos from today: a Polystachya orchid in bloom with another on the same branch showing buds; one of two Tillandsia utriculatas with flower stalks that had fallen onto the trail and which I put up into trees, although much lower than they originally
were; and an Eastern Pondhawk eating a Halloween Pennant. I was just getting ready to photograph the pennant when the pondhawk swooped down, grabbed it, and flew to another perch.

Totally absent this week were Common Green Darners after there were 18 last week, and Limpkins when there were a half dozen last week and also the week before.

Wildfile Q & A: Bird Call Vs. Bird Song

A Carolina Wren sings to define and defend its territory.

Q: What are the differences between a bird call and a bird song?

A young Red-bellied Woodpecker calls to its parent for food.
A young Red-bellied Woodpecker calls to its parent for food.

A: A bird call tends to serve a specific function and is primarily
innate rather than learned. A bird song is almost always learned and
is often customized by individual males.

EXAMPLES OF CALLS

Alarm calls alert every bird within hearing range that danger is
present, and all innately understand what the call means and act
accordingly. The alarm call of one species can be recognized by birds
of many other species.

Location calls let mates or birds in a flock know where the others
are. For example, when a Barred Owl calls during the day, a mate often
answers, sometimes from a good distance away. Each then knows where
the other is. Location calls can also identify good feeding and
nesting habitats.

A chick’s “feed me” call triggers a parental response to find and
bring food to its offspring. As the chicks get older, begging behavior
complements the call for food.

A Carolina Wren sings to define and defend its territory.

A Carolina Wren sings to define and defend its territory.

EXAMPLES OF SONGS

Male birds tend to sing more than females, and unmated males sing more
than mated ones. Males use songs to attract mates and to identify and
defend territory. The song warns other males to stay out of its
territory, and it invites females to come in. Males can recognize the
songs of neighbors and usually don’t pay any attention to them, but
they sing furiously if they hear the song of a stranger who might
enter their territory.

In selecting a mate, females may use the size and complexity of the
song to determine a male’s potential fitness as a partner. More mature
males usually have more elaborate songs which may indicate to the
female that the male is a survivor with more breeding experience and
better health.

A majority of songbirds have at least two different songs. The extreme
singer is the male Brown Thrasher which is estimated to have over
3,000 song types.

Wildlife Q & A: How can you tell if an alligator is male or female?

Baby alligators stay close to their mother for protection.

Q: How can you tell if an alligator is male or female?

Baby alligators stay close to their mother for protection.
Baby alligators stay close to their mother for protection.

A: There are three ways. Two are easy; the third is not.

The first easy way is to gauge the length of an adult alligator. If it measures 10 feet or more, it’s a male. Females don’t grow that long. If it’s less than 9 feet in length, it could be either a male or a female.

The second easy way is to see if there are lots of small, newly born alligators around the adult. They will stay by their mother for up to a year and she will protect them. A male gator could eat them, even if he’s the father, so the mother usually won’t let him anywhere near the babies.

There are minor physical differences in head and body shape, but basing a decision on those alone is risky at best.

So much for the easy.

To be absolutely certain of an alligator’s gender, it’s necessary to either feel or visually identify the copulatory organs that are hidden inside the alligator’s body in the cloaca, or vent, on the animal’s belly. It is a slit located between the rear legs.

For newly hatched gators, the sex organs can only be seen with a magnifying glass. The baby gator is turned on its back, the vent is opened using a tweezers, and the organs are illuminated by a magnifying glass. If they fill the entire cloaca and are dark pink to
dark red, it’s a male. Female organs are half that size and are light pink or white.

For a larger alligator, the gator must be flipped over and a person must insert a clean finger into the vent and feel for the copulatory organ which is pulled out, measured and examined. This procedure does not harm the alligator if performed correctly; however, large alligators don’t allow themselves to endure such a demeaning intrusion.

So unless an alligator is over 10 feet long or it is protecting baby gators, there’s no way to be sure if an alligator is male or female.

PRESS RELEASE: SOUTHERN CREW RESTORATION PROJECT

Flint Pen

PRESS RELEASE: June 29, 2015

CONTACT: DEP Press Office, 850.245.2112, DEPNews@dep.state.fl.us

SOUTHERN CREW RESTORATION PROJECT CLEARS ANOTHER HURDLE

~Project phase will restore wetlands, provide flood protection and increase water storage~

LEE COUNTY, Fla. – The Florida Department of Environmental Protection has authorized the South Florida Water Management District (SFWMD) to continue the next phase of the Southern Corkscrew Regional Ecosystem Watershed (CREW) Restoration Project. When completed, the project will provide significant benefits to the ecosystem including restoring wetlands and the natural sheetflow of water, improving regional flood protection drainage, increasing water storage and aquifer recharge capability, and reducing the amount of nutrient-rich stormwater reaching the Imperial River and Estero Bay.

“This project exemplifies the commitment of the state of Florida to protecting and restoring the larger south Florida ecosystem,” said DEP Deputy Secretary for Ecosystem Restoration Drew Bartlett. “The department will continue to work closely with our partners to ensure that restoration continues.”

The authorization issued today is for Phase II of the Southern CREW Restoration Project which encompasses 4,150 acres of multiple native plant communities, including hydric pine flatwoods, strand swamps, wet prairies and marshes that have been fragmented by past construction of ditches and roads. These alterations have resulted in restriction of historic sheetflow, artificial water impoundments and flooding, increased pollutant loading to the Imperial River, an Outstanding Florida Water, and disruption of natural wetland functions.

“The project will restore the southwest corner of the larger CREW project,” said SFWMD Governing Boardmember Rick Barber. “The restoration in this particular location creates a vital buffer area between the CREW project and the eastern urban boundary.”

Phase II of the project consists of ditch backfilling, ditch plugging, road degradation and the construction of low water crossings to allow for the re-establishment of hydrologic conditions similar to those present prior to development attempts of the area in the 1960s. The project is expected to restore approximately 437 acres of wetlands. The project’s enhancements are anticipated to encourage the growth and sustainability of native wetland plant species, providing both food and habitat for wildlife.

The Southern CREW Restoration Project is located in Lee County between the Kehl Canal, which is located adjacent to the northern boundary, east of Interstate 75 and north of Bonita Beach Road.

A View of Bird Rookery Swamp-“Great day for butterflies”

Below are first hand observations from our volunteer Dick Brewer. Who does weekly visits to Bird Rookery Swamp and very week sends us incredible stories of the magical 12 mile loop. If you would like to see more of his observations visit: http://www.dickbrewer.org/CREW.html

“Below are observations from BRS on June 6. Great day for butterflies with 19 species identified, plus three more skippers that I don’t know and haven’t identified. The attached photo shows two Silver-spotted Skippers, one Dun Skipper, and one Ruddy Daggerwing all feeding on the same Buttonbush plant.

The juvenile Barred Owl was on a limb over the pond at marker 6. It flew down into the grass one time where it caught and ate something very small; then, it flew back up to its limb and began hissing for an adult to bring it more food.

The otter family was in a water hold blanketed with Duckweed but each otter was quite successful at catching fish. The second photo shows one of the otters really chewing a fish it caught, first on one side of its mouth, then the other, and finally chomping with both sides.
The tail of the fish is still hanging out of the right side of its mouth in the fourth panel.

Otter
By Dick Brewer

Bird Rookery Swamp observations
Saturday, May 23 ~ 7:15 am–1:00 pm

“It was a so-so day for birds but a great day for butterflies and mammals, River Otters especially. I saw seven– a family of five and two other individuals in separate places. The family retreated into what was probably their den in two fallen tree trunks, a nice
two-story place. Once inside, there was some grunting and huffing, and two of the juveniles peeked out, one from the second story and one from the ground level (photo). Another young otter was on its own a little past Ida’s Pond and alternated between catching fish and
watching people watch it.

The Water Moccasin was between markers 6 and 3. It was small, perhaps three feet, but it was easily irritated because it was ready to shed its skin. The milky blue eyes meant it was close to sightless, so it over reacted to any movement, sound or vibration. A couple from South
America bicycled by as I was watching the snake; the husband stopped but when his wife heard the word “snake,” she put her head down and quickly pedaled on by. He said snakes were not on her favorite critter list.
