Connections are a common theme on this program. We've talked about broad connections such as those linking clean water to healthy fish, wildlife, and human populations. Widespread education about more specific connections like the one between monarch butterflies and wild milkweeds have resulted in concerted efforts to benefit these species. Edification of the detrimental impacts of balloon releases on wildlife is another example of spreading the word about connections, negative ones in this case.
Continuing in this vein, today's program is about another natural connection unknown to most people. It involves hummingbirds, a favorite subject of birdwatchers if measured by the number of hummingbird feeders sold annually.
