Brown Pelicans in Tampa — Tampa, Florida

The brown pelican (Pelecanus occidentalis) is a year-round resident of Tampa Bay, the shallow warm estuary that forms the western edge of Tampa, Hillsborough County's county seat. The city's flat, low-lying coastline — fringed with mangrove islands and estuarine channels — provides both foraging and nesting habitat that the Florida Fish and Wildlife Conservation Commission (FWC) identifies as characteristic for the species. Brown pelicans nest in colonies of several hundred pairs in mangroves and congregate in large numbers at fishing piers along the bay's shores and at its mouth.

Tampa Bay's role as a nationally significant brown pelican concentration site is documented most precisely at the Sunshine Skyway Fishing Piers State Park, located at the mouth of Tampa Bay where the Sunshine Skyway Bridge spans the gap between Hillsborough and Manatee counties. Research published in Avian Conservation and Ecology in 2026 found that approximately one-third of all rehabilitated pelicans in the region originated from those two piers, and a 2019–2020 survey documented an average of approximately five entangled live and dead brown pelicans per survey at the southern pier alone. The site has consequently drawn organized management responses from FWC, Tampa Audubon, and academic researchers over more than a decade.

The FWC species profile describes the brown pelican as nesting primarily in mangroves in Florida, where colonies of several hundred pairs are typical. Tampa Bay's estuarine islands offer precisely the low-disturbance mangrove structure these colonies require. The species is also protected statewide and federally under the U.S. Migratory Bird Treaty Act regardless of its listed status under Florida law.

Florida's regulatory treatment of the brown pelican has shifted over time. The Florida Natural Areas Inventory (FNAI) Field Guide (2000) assigned the species a Florida state rank of S3 (Rare) and a global rank of G4 (Apparently Secure), reflecting a population that had recovered substantially from mid-twentieth-century lows but remained regionally variable. FWC removed the brown pelican from Florida's list of state-designated species in January 2017, though the agency subsequently included it in the Imperiled Species Management Plan, signaling continued management concern. The FWC 2013 Species Action Plan, documented by Bay Soundings, identified fishing gear entanglement and habitat disturbance as the primary documented threats to the Florida population.

Breeding population estimates for Florida, as documented by FNAI, ranged from 6,000 to 8,000 pairs in the 1970s, peaked at 12,310 pairs in 1989, and stood at approximately 9,950 pairs as of 1995. FNAI also documented a pattern of population decline in areas south of Tampa Bay, making the Tampa Bay region a comparatively stable portion of the species' Florida range.

The Sunshine Skyway Fishing Piers State Park comprises two car-accessible piers formed from the old Sunshine Skyway Bridge structure. As described in Avian Conservation and Ecology (2026), the piers together span 4.4 kilometers — more than 2.5 miles — at the mouth of Tampa Bay. The structure attracts large numbers of anglers year-round, and brown pelicans congregate at the piers to scavenge bait fish and discarded catch, creating conditions where fishing line and hook entanglement occurs at documented high rates.

Research by Dr. Elizabeth Forys of Eckerd College, cited in Bay Soundings, identified the Sunshine Skyway piers as the highest-entanglement fishing pier in studies of the Tampa Bay area. A 2019–2020 survey documented an average of approximately five entangled live and dead brown pelicans per survey visit at the southern pier alone, according to Avian Conservation and Ecology (2026). The same study found that approximately one-third of all rehabilitated pelicans in the regional population originated from the Skyway piers, establishing the site as a disproportionate driver of regional pelican injury and mortality.

Fishing line entanglement has been recognized as the primary cause of brown pelican mortality in Florida since research conducted by Ralph Schreiber in Tampa Bay during the 1970s and 1980s, as documented by Bay Soundings. Entangled pelicans suffer lacerations, limb loss, and drowning; birds that escape with embedded hooks or wrapped monofilament frequently die from secondary infection or starvation before rescue is possible.

FWC convened the Hooked Pelican Working Group to coordinate responses to pelican entanglement across Florida fishing piers, and in 2013 developed a formal Species Action Plan identifying entanglement reduction as a management priority, according to Bay Soundings. The Working Group brought together FWC, wildlife rehabilitators, researchers, and volunteer organizations to document the problem and develop site-specific interventions.

Tampa Audubon, the local chapter of the National Audubon Society, has maintained an active rescue presence at the Sunshine Skyway Fishing Pier since 2013, when volunteers began systematically capturing and removing fishing gear from ensnared pelicans on-site, as documented by Bay Soundings. This volunteer-led intervention predates the formal FWC regulatory measures enacted a decade later and represents one of the more sustained community-based wildlife rescue programs at a single Florida site.

The management measures deployed at the Skyway piers as of 2023–2025, as described in a study published in PMC / National Library of Medicine (2025), include a seasonal ban on high-risk fishing gear during the pelican breeding season, installation of fishing line disposal bins, educational campaigns directed at anglers, and placement of on-site rescuers. The same study noted that angler and public response to the regulations was mixed, and that FWC had committed to continued monitoring to assess the effectiveness of the measures. The 2025 PMC study framed angler perceptions as a key variable in the long-term outcome of pier-based entanglement management programs.

On November 15, 2023, FWC enacted new seasonal fishing gear restrictions at Sunshine Skyway Fishing Piers State Park specifically designed to reduce brown pelican entanglement during the breeding season, as documented by Avian Conservation and Ecology (2026). The restrictions represented the most formal regulatory action taken at the Skyway piers in the documented history of pelican management at the site, following more than a decade of volunteer rescue activity and stakeholder coordination through the Hooked Pelican Working Group.

Research published in Avian Conservation and Ecology in 2026 provided a comparative analysis of rehabilitation admissions from the Skyway piers, confirming the site's outsized contribution to regional pelican injury statistics and examining the piers' structure and angler density as factors in entanglement rates. A companion study published in PMC in 2025 documented angler perceptions of pelican entanglement at Tampa Bay piers, identifying communication and engagement strategies that researchers identified as opportunities for improving conservation outcomes at pier sites.

As of May 2026, the effectiveness of the November 2023 gear restrictions remained under active monitoring by FWC, with no peer-reviewed outcome assessment yet published for the full post-regulation period.

Tampa Bay functions as an anchor site for brown pelican conservation within Florida's Gulf Coast corridor. The FNAI Field Guide (2000) documented population declines in areas south of Tampa Bay while noting comparatively stable conditions in the Tampa Bay region, making the bay an important reference point in statewide population monitoring. FWC's species profile describes Tampa Bay's mangrove-fringed estuarine islands as representative of the primary nesting habitat type for Florida's brown pelican population.

The Sunshine Skyway Bridge connecting Hillsborough and Manatee counties at the bay's mouth creates a geographic choke point where pelicans, anglers, and recreational infrastructure converge at high density. The piers' position spanning two counties means that management coordination involves both Hillsborough County and Manatee County jurisdictions, as well as the Florida Department of Environmental Protection, which administers Sunshine Skyway Fishing Piers State Park, and FWC, which holds wildlife regulatory authority. Pinellas County, across Tampa Bay to the west, contains additional pelican habitat within the broader Tampa Bay estuarine system.

The Tampa Bay case has drawn attention in the peer-reviewed literature as a model for studying the intersection of high-use recreational fishing infrastructure and colonial waterbird welfare. The two studies published in 2025 and 2026 — one in PMC and one in Avian Conservation and Ecology — both used the Skyway piers as their primary study site, reflecting the site's documented significance in national discussions of pier-based seabird conservation management.
