Transcript of How Does the increase of Development harming migratory birds

How is increased development harming migratory birds and butterflies
causes of ecosystems endangerment
increase in human development = decrease in bird habitats
birds adjust by living in habitats that are also inhabited by humans
living too close to migratory birds brings the dilemma of H5N1 (bird flu)
H5N1 could infect species other than the birds
no known vaccine for H5N1
no known disease found in migratory butterflies
no major consequences besides possible extinction of a beautiful animal

How is increased development harming migratory birds and butterflies?
We would like to extend our thanks to you for watching
what can we do to help
our class could symbolically adopt a monarch to donate to the WWF
promote tree nurseries (restore forests)
have bake sales and other fundraisers to raise money for bird de-extinction foundations
Attend annual meeting for the Stamford land conservation and trust on October 22 at 6:30 pm

Habitat loss
migrate to mountain forests to reproduce & feed
humans rely on mountain forests for agriculture & tourism
chemicals being used by humans that limit milkweed, their main source of food
Climate change
migrating less and less to Mexico because of wet winters
some are dying before migrating in the US & Canada because of untypical weather patterns (drought, rainfall)
like to live in:
many obstacles for survival (many of them being human disturbances):
small breeding & feeding ranges
predators (cats, goats, rats, mongoose)
habitat loss
land conversion (grassland & trees to sugarcane plantation, deforestation)
originally small population
climate change/storms/weather/natural disasters
illegal acts (hunting, bird trades, egg collections)
pesticides & chemicals
loss of food source
whats going to be in the powerpoint
losing bird & butterfly population
possibility of catching diseases
loss in animal habitat
loss of prey
Bird Species at Risk
some migratory birds that are endangered include:
Amsterdam Island Albatross
Bachmann's Warbler
Chinese Crested Tern
Orange-Bellied Parrot
Butterfly Species At Risk
