Field Notes

These updates from our field biologists discuss the movements and activities of individual Florida panthers. Biologists use prefixes and numbers to identify each cat.

Panther Identification

When a kitten is handled at the den a transponder is inserted under the skin which permanently identifies that individual and it receives a "K" number. When a panther is captured and wears a radio collar it gets an "FP" number. FP just stands for Florida panther; they are numbered sequentially as they're captured. A panther that has never been handled at the den or captured for placement of a radio collar is identified as an uncollared Florida panther and has the designation "UCFP."

Mortality Causes
IA = intraspecific aggression (panthers killing panthers)
RK = road kill

Location
BCNP = Big Cypress National Preserve (specific units within BCNP include Add Lands, Bear Island)
FPNWR = Florida Panther National Wildlife Refuge
OSSF = Okaloacoochee Slough State Forest
SIR = Seminole Indian Reservation
ENP = Everglades National Park
FSSP = Fakahatchee Strand State Preserve
CREW = Corkscrew Regional Ecosystem Watershed
PSSF = Picayune Strand State Forest
CSS = Corkscrew Swamp Sanctuary

October-November 2008 Field Notes

11/30/08

We started our 2008/2009 capture season at Okaloacoochee Slough State Forest (OK Slough) on November 24th. That same day a new young male, FP165, was captured, weighing in at 100 pounds. As a yearling, he was still traveling with a brother and mother. Read More

April - June 2007 Field Notes

6/30/07

On April 16 our Panther Section Team Leader, Darrell Land, saw an uncollared male panther walking along side female FP110 while conducting the telemetry flight. This was especially curious because FP110 had four one-month-old kittens back at the den. Read More

January-March 2007 Field Notes

3/30/07

Florida Panther #147 is approaching 2 years old and, as is typical of dispersing aged males, has been exploring some new territory. Born in Big Cypress National Preserve, he gradually worked his way west through Fakahatchee Strand Preserve State Park and Picayune Strand State Forest. Read More

September-December 2006 Field Notes

2/28/07

Male FP135 and male FP131 were located very close together in mid October during one of our routine monitoring flights. We suspected they had an altercation and guessed a female was the catalyst. Both of these males’ territories overlap each other so they undoubtedly have met before. Read More
