How has DDT affected raptor populations?
Osprey were most susceptible because they were higher up the food chain. *DDT runoff into streams *Minnows, crayfish, insects consumed some *Small fish ate those creatures, and so got an additive dose of all the DDT they were carrying *Larger fish ate the smaller ones and, again, the DDT load of each smaller fish added to that *Osprey consume large fish. THUS the osprey, as an end predator consumed the most DDT. Factor in that, the higher up the food chain you go, the fewer individuals there are. The DDT made the eggshells fragile, so fewer osprey were hatched. So their numbers were reduced even more in comparison to those organisms that were more abundant to begin with.
Why is DDT harmful to osprey?
Dichlorodiphenyltrichloroethane (DDT) is a pesticide that proved very harmful to the environment. It entered the food chain and even affected humans. It caused bird eggs to become thin shelled and brittle, with many eggs being crushed when the parent bird tried to sit on them in the nest.
Why would water plants contain DDT?
Some of the pesticides sprayed on farm crops wash off in the rain and get into the waterways. The water plants absorb the pesticides.
What chemicals affect peregrine falcons?
DDT was a large threat, I do not know of any others.
Do chemical poisons in the bald eagles food cause eggs to crack before incubation is complete?
Yes. Farmers used a chemical called DDT on their crops as an insecticide This chemical would leak into the ground and pollute the water, eventually the fish in the water were poisoned and the eagles that ate the fish consumed large amounts of DDT due to biomagnification. Then when the eagles laid eggs, the DDT caused the shells off the eggs to be softer so when the mother eagle was incubating her eggs, they would be crushed.
Is there any evidence of bio-accumulation in the case of DDT?
Yes, many animals and plants have been tested and proven to contain DDT years after it was applied to crops many miles away. The most notable case is that of the American Bald Eagle, whose eggshells were weakened by DDT contamination, threatening the entire Bald Eagle population for years. Some years after DDT was banned in the US, the eagle's normal reproductive cycle was restored, as the DDT levels in their blood was reduced.
