Alternative Text Description for Florida Scrub-Jay Distribution Map

TABLE OF CONTENTS

MAP OVERVIEW

This map displays the distribution of Florida Scrub-Jay occurrences across peninsular Florida based on citizen science observations. The Florida Scrub-Jay is a federally threatened species and represents one of the highest priority bird species in the Peninsular Florida Bird Conservation Region. The map shows where individual birds have been observed and reported through the eBird citizen science project, revealing the current known range of this species across the state.

GEOGRAPHIC CONTEXT

The map covers the entire state of Florida, from the Panhandle region in the northwest to the southern tip near Cape Coral. Major cities visible on the map include Tampa and St. Petersburg on the west coast, Orlando in the central region, Gainesville in the north-central area, Palm Coast on the northeast coast, Lakeland in the central region, Clearwater on the west coast, Sarasota on the southwest coast, West Palm Beach on the southeast coast, and Immokalee in the southwest interior. Lake Okeechobee is visible as a prominent water body in the south-central portion of the state. The map extends from the Gulf of America coastline on the west to the Atlantic Ocean coastline on the east.

KEY INSIGHTS

Florida Scrub-Jay observations show a distinctly fragmented distribution pattern across peninsular Florida, indicating habitat specialization and limited range. The highest concentrations of observations occur in several discrete clusters: a large concentration in the central highlands region between Orlando and Lakeland, a substantial cluster along the Atlantic coast from Palm Coast southward through the Space Coast area, a notable concentration in the Ocala area north of Orlando, and scattered populations along portions of the Gulf of America coast near Sarasota and south of Tampa. The species is notably absent from much of southern Florida below Lake Okeechobee, the extreme northern panhandle regions, and many coastal areas. The fragmented pattern reflects the species' dependence on specific scrub habitat types that occur in isolated patches across the peninsula.

Florida Scrub-Jay Observation Points (red outlined square symbols with diagonal crossed lines)

Appearance:

Each observation is represented by a square symbol with a red outline and diagonal lines crossing through the interior, creating an X-pattern within each square.

Distribution:

Observations are concentrated in several distinct geographic clusters across peninsular Florida, with the densest aggregations occurring in the central ridge region, along portions of the Atlantic coast, and in scattered locations along the Gulf of America coast. Many areas of the state show no observations.

Notable locations:

The largest continuous concentration occurs in the region between Orlando, Lakeland, and areas to the north and west of Orlando, where symbols appear in tightly packed clusters. A second major concentration extends along the Atlantic coast from approximately Palm Coast southward through Brevard County. Significant clusters also appear in the Ocala National Forest area north of Orlando, near Sarasota on the southwest coast, and in scattered locations south of Tampa. Isolated observations appear near Gainesville, along portions of the panhandle coast, and in various interior locations.

Spatial patterns:

The observation points display a distinctly clustered and fragmented pattern rather than a continuous distribution. Clusters often appear linear or elongated, particularly along the Atlantic coastal ridge. Dense aggregations of overlapping symbols indicate areas of repeated observations or high observer effort. The spacing between major population centers suggests geographic isolation between subpopulations. The absence of observations across large portions of the state, particularly in southern Florida and many coastal areas, creates a pattern of habitat islands separated by unsuitable areas.

Overlapping Patterns

In areas of highest concentration, particularly in the central highlands and along the Atlantic coast, individual symbols overlap extensively, creating dense patches where precise individual point locations become difficult to distinguish. These areas of high symbol density likely represent either true population concentrations, areas of intensive observer coverage, or both.

SYMBOL GUIDE

ADDITIONAL INFORMATION

This map represents occurrence data rather than a range map or habitat suitability model. The presence of observation points indicates where the species has been documented, while the absence of points may indicate either true absence of the species or lack of observer coverage in those areas. The Florida Scrub-Jay is habitat-specific, requiring scrub oak ecosystems that occur in fragmented patches across Florida. The distribution pattern shown reflects both the natural fragmentation of suitable habitat and the species' limited dispersal ability. As a federally threatened species, the Florida Scrub-Jay is endemic to Florida and found nowhere else in the world. The clustered observation pattern likely reflects both the species' biology and areas where birdwatchers actively survey and report observations through eBird.

DATA CONTEXT

Data Source:

The occurrence data is derived from the EOD – eBird Observation Dataset, a biodiversity-related citizen science project managed by the Cornell Lab of Ornithology. Data was downloaded using the Global Biodiversity Information Facility (GBIF) API. This dataset was compiled by the Florida Fish and Wildlife Conservation Commission (FWC) for highest priority bird species in the Peninsular Florida Bird Conservation Region (BCR 31). Data source layer name: EBIRD_DEC24.

Definition Query:

The data displayed is filtered to show only observations where DESCRIPT = 'FLORIDA SCRUB-JAY', representing occurrence records specifically for this federally threatened species.

Scale Information:

The map displays statewide coverage at a scale appropriate for viewing the entire state of Florida and understanding the broad geographic distribution pattern of the species across its range.

Coordinate System:

NAD_1983_HARN_Florida_GDL_Albers (WKID 3087).

Time Period of Content:

The observation data spans from January 1, 2019 to December 31, 2024, representing approximately six years of citizen science observations.

Limitations:

As citizen science data, observation records reflect both species presence and observer effort. Areas without observations may indicate true species absence, unsuitable habitat, or simply lack of observer coverage. The dataset does not represent a systematic survey and may be biased toward areas with higher human population density or accessibility. The data does not distinguish between single observations and multiple observations of the same individuals. Observation density may reflect birding hotspots or popular observation locations rather than actual population density.

Map Coverage:

The map covers the entire state of Florida, extending from the panhandle region in the northwest through the full length of the peninsula to the southern tip. Coverage includes both coastal and interior regions across the state.
