"To try and help pelicans survive,
scientists removed some from the wild,
placed them in zoos,
and fed them food free of DDT.
Fragile eggs were warmed away from parents
so shells wouldn't
crack and break."
In a new release from the books for a better earth series, readers learn about the scientists who work diligently to solve mysteries in the natural world. This research was concerned with dwindling numbers of brown pelicans. In the 1950s, there was worry that fewer pelican chicks were being born, and it was noted that it was also happening with bald eagles, raptors, and other birds of prey.
Focusing on the pelicans, scientists set to work to try to understand what was causing the loss. The first clue was that the eggshells were not strong enough to hold the weight of the parents who were sitting on them. How could that be? Making connections led to the fact that DDT was being found in water and soil ... and in the animals pelicans ate. It was in every part of the food web.
Taking some pelicans into captivity to provide them with food free of the pesticide, and to incubate fragile eggs, the scientists pleaded that the spraying be stopped. Although she is not mentioned, the work of Rachel Carson was the catalyst needed to bring awareness and change. It took people protesting and government action. The pelican population improved over the next thirty-seven years, until they were no longer in danger of extinction.
Unfortunately, the same cannot be said for the many other plants and animals that are at risk today.
"Pollinators dwindle as food sources disappear.
Songbirds struggle to find a suitable spot to hatch their young.
Marine life gobble garbage.
Yet there is hope."
The work that helped the pelican can continue to fight against climate change and habitat loss. It takes constant work and concerned citizens to speak out and work toward change.
This tribute to the hard-working scientists who worked diligently to solve a mystery is written in clear and compassionate language, and is accompanied by appealing gouache and acrylic illustrations sure to engage young readers. Backmatter is very useful, and includes the effects of DDT, where to learn more about the brown pelican, a glossary, a bibliography, and an index.
