  2. 5) Decrease predation- Major source of nest loss A) Nest predators

  3. How to Avoid Predation? • Crypsis of eggs or parent • Location – Cliffs, islands • Floating nests • Cavities • Thin Tree Limbs • 3)Safety in Numbers - Coloniality • Deception yellow-rumped thornbill • “Hired Gun” tropical wrens

  5. Violet-green Swallow Tree Swallow Secondary cavity nesters

  6. Mud nests Cup nest Barn Swallows

  7. Retort mud nest - Cliff and Cave Swallows

  8. Genetic analysis reveals evolutionary relationships reflected by nests

  9. Apodiformes- swifts - convergent on swallows but related to hummers!

  10. Apodiformes- Edible (White-nest) and Black-nest Swiftlets Cave dwelling swiflets of SE Asia birds that think they are bats Echolocating, insectivorous cave dwellers Double “echo click”

  11. Verdin Common Bushtit

  12. Nest building is both Innate and refined through learning Fig 16-6 and 16-7
