The 2019-2020 season is the 13th consecutive year for eagles to nest on the island. Historically, there was a nest reported at the Scharrer homestead, and the female eagle was reported to have been shot on the nest, according to a Clearwater Sun article and notes from Myrtle Scharrer Betz in 1935. This new nesting occurance was the first time eagles have reestablished nesting on the island since the 1935 homestead nest.
Eagles may live up to 40 years. Once mating occurs, after 5 days of internal gestation, the first leg is ready to be laid. Eggs are laid 36 hours apart, Both male and female incubate. Average gestation in the egg is 35 days, with eggs hatching one at a time 36 hours apart. Eaglets remain in nest 10 to 12 weeks. Both parents feed young. Fledglings broaden their range slightly away from the nest over a period of 4 to 8 weeks. Young become independent of parents for food at approximately 17 to 20 weeks.

2 resident adult Great Horned Owls are present on the island this season. They again selected the same previous osprey nest used used 2 years ago. The site is .3 miles from the trailhead on the west side of the trail.
Mating occurs in late December to January. 3 to 4 eggs are laid in January or February. Incubation averages 28 to 35 days. They hatch over a period of time corresponding to the time the eggs were laid. The female incubates while the male hunts and protects the nest. He continues to fend for the family once the owlets hatch. Owlets open eyes at 1 week. They first leave nest in 4 to 5 weeks. They remain nest the nest and fledge fully at 10 weeks. They will remain perched on limbs, and in their parents are for up to 1 year, when they are then sexually mature.

Osprey Nesting 2016-2017: 13 Active Nests
Nesting season runs from May through October. Daily beach patrols are conducted during this time, and nests are protected by a wire cage to prevent predation from raccoons, ghost crabs, and other would be predators, and to prevent disturbance by beach goers. Loggerheads prefer the warmer sandy beach areas further south of here. The barrier islands this far north along the west coast are typically not heavily used nesting sites, and for this reason only a few Loggerhead nests are observed on our Islands each year. It is estimated that only 1 in 1000 hatchlings survive to adulthood. Part of the survival success depends upon natural resource management practices.
Loggerhead Sea Turtle Nesting 2019-2020: 9 at Anclote Key - 14 at Honeymoon with lots of raccoon predation - 10 at Caladesi - 65+ at Egmont Key
Loggerhead Sea Turtle Nesting 2018-2019: 6 Honeymoon Island - 8 Caladesi - 10 Anclote - 118 Egmont Key
Loggerhead Sea Turtle Nesting 2017: 2 Honeymoon Island - 6 Caladesi - 1 Anclote

Kemp's Ridley Sea Turtle Nesting Activity
Named for avid fisherman and naturalist Richard Kemp of Key West. Typically, this tropical species is not observed nesting here. They nest en mass in armadas, on windy days at Rancho Nuevo in the Mexican state of Tamaulipas. They do, however commonly migrate throughout the Gulf of Mexico from April thru September, and are sometimes seen as far north as Nova Scotia. Again, they typically do not nest in these areas. There are reports of sightings in Ireland as well. Juveniles have a vast deeper water range, with adults found in a more limited nearshore range. They reach maturity as sub adults at 12 years. It is a rare and critically endangered species, primarily due to human activities such as egg poaching, trawl nets, gill nets, entanglement, and boat strikes.
There was a previous incident of nesting in 2015 at Caladesi, and also in 2007 at Anclote, and this year's nest is the 2nd known case at Caladesi. They are daytime nesters, with the nesting process taking only 45 minutes on average. Adults grow to about 2 feet in length and an average weight of 89 lbs. They feed in shallow waters and as juveniles they feed at the weed line and floating mats of sargassum weed, whereby adults are primarily bottom feeders and prefer crabs and some mollusks, jellyfish and urchins.
Kemp's Ridley Sea Turtle Nesting 2019 - 2020: None observed on the islands this season.

2017 Shorebird Nesting Season
05/25/17 - An American Oystercather nest site has been observed at Honeymoon north beach.
06/02/17 - Snowy Plover and Wilson's Plover chicks have hatched.
2016 Shorebird Nesting Season
End of season update from August 2016 - Shorebirds are fledging right now. The Three Rooker colonies hatched over 10,000 laughing gull chicks, 1000 Royal tern, 250 Sandwich tern, 250 Black skimmer, and 20 Caspian tern. Anclote Key always has the high numbers for Wilson’s and Snowy Plovers, easily 30 juveniles seen there last count. American Oystercatchers are having a 2nd bad year in a row, 7 nesting attempts, 5 chicks hatched, none have survived to fledge. Predators and overwash are the two biggest known factors affecting success. One final round of surveys this week to look for more chicks!
