  5. Life History of Florida Shorebirds

  6. With 217 species worldwide and approximately 50 species that breed in North America, shorebirds make up a small percentage of the world’s more than 8,000 bird species

  7. They can be found all year round on most Florida beaches.

  8. Breeding Season

  9. The Florida breeding season is March - July

  10. 14 Species of shorebirds and seabirds nest in Florida

  11. The majority of shorebirds leave Florida to nest in the Arctic, Midwest or the North Atlantic Coast

  12. In Florida, shorebirds and seabirds nest on coastal beaches, barrier islands, spoil islands, causeways, gravel roofs, coral rock islands

  13. Nesting Birds

  14. Colonial Nesting– ‘seabirds’ gulls, skimmers, terns

  15. Enhanced protection and defense against predators

  16. Improved foraging – follow successful hunters to food source

  17. Solitary Nesting – shorebirds (oystercatchers, willets, plovers)

  18. Use camouflage for protection from predators

  19. Food resource remains more constant in area of territory

  20. Colonial Nesting Birds

  21. Nesting ‘Seabird’ Status – 10 Species

  22. Threatened – Least Tern, Roseate Tern

  23. Petitioned for listing – Gull-billed Tern

  24. Species of Special Concern in Fl- Black Skimmer, Sooty Tern, Royal Tern, Caspian Tern, Sandwich Tern, Brown Noddy

  25. Common- Laughing Gull

  26. Colonies on ground or rooftops

  27. Loss of habitat on beach

  28. Many coastal buildings are getting rid of gravel rooftops

  29. Human disturbance on ground

  30. Risk of chicks falling off roof

  31. Least Tern – Only tern that will nest on rooftops in FL

  32. Roofs support 75% of all colonies and 83% of all nests

  33. Black Skimmer – Starting to nest more on rooftops in FL

  34. 10% of nests are on roofs

  35. Solitary Nesting Birds

  36. Four shorebird species nest in FL

  37. Snowy Plover (threatened), American Oystercatcher (threatened), Willet (common), Wilson’s Plover (species of special concern)

  38. Advantages of solitary nesting

  39. Use of camouflage for predator protection (instead of colony)

  40. Food resource remains more constant

  41. Snowy Plover Nest Monitoring

  42. USFWS census and WEC Master’s student Raya Pruner

  43. Information about population, nest success, nesting distribution and relative survival

  44. Occur on mainly the Gulf Coast

  45. American Oystercatcher Nest Monitoring

  46. Determine nest success, relative survival and distribution of Florida birds

  47. Provide information to managers

  48. Occur throughout coastal Florida

  49. Wintering Shorebirds

  50. About 20 species of shorebirds winter in Florida annually
