Frog Sounds One of the happiest sounds I ever hear (especially after a long cold winter like this one!) is the delightful peeping of the spring peepers (Hyla crucifer). You can hear them in most places where an ephemeral pond has collected snowmelt and spring showers. These ponds usually form due to the relatively high water table in spring months, and are usually gone by early June at the latest. The peeping sounds are quite loud, and I suppose annoy some people, but it is a lovely way to be lulled to sleep for me. Those lucky enough to see one will see an X mark on their backs. It amazes me that an animal about the size of a quarter can make such noise.Usually at about the same time you hear the 'peepers', some ponds may be filled with the wildly active wood frog (Rana sylvatica). His sound is likened to quacking or clucking. The first time I ever heard their music, I walked down along the river to look for the flock of ducks, and found the sound was coming from a small pond behind me as I faced the river. What a delight it is to see! The male frog calls (quacks) to draw the females from their woodland home for a few days of mating and egg-laying. The males look quite dark compared to the females, and the females have what looks like part of a Zorro-like mask behind the eyes. Walking along the river bank near our house on the Cacapon in later April and May, you may hear a pickerel frog (Rana palustris). In our family we jokingly call them the 'Ralph Kramden belly' frogs. The sound is low and reminds us of the hapless bus driver's pain sound 'w-a-a-a-a-a' when he has a belly ache or pretends to have one. Another low-pitched frog is the bull frog (Rana catesbeiana) whose 'ba-rump ba-rump ba-rump' is familiar from May through July. They are the largest North American frog. They lay eggs in the river and the tadpoles take two years to mature into frogs. One night when the ephemeral pond near our Cacapon house was filled with water from a recent rain, we snuck up on several calling 'tree frogs'. It is my belief they were gray tree frogs (Hyla versicolor). These animals are very loud, and most people think that birds are making the noise. Usually by summer they are high in the tree-tops and will often call a few times during or after a summer rain. They are warty looking and variable in color, sometimes mimicking their environment. Their eggs hatch in a week, and it takes two months for the tadpoles to mature. The green frog (Rana clamitans) looks a little like a small bull frog. It can be distinguished at sight by the small ridges from the nose back through the eye and to the rear of the frog. These ridges are absent in the bull frog. They have a characteristic call which certainly differs from the bull frog, as it sounds a little like a deep banjo string when plucked. One quick 'bwang', sometimes repeated. The American toad (Bufo americanus) though not a frog, has an audible sound also. It has a dry, warty skin, unlike the slimy skin of a frog. The male makes a long trilling sound as he tries to attract a mate. If you hear several in a pond, you can usually distinguish the different pitches from each individual. They seem to call and answer each other, but it is really a competition to attract a female. All over the Earth, amphibian populations are in decline. What can you do to help them? Don't disturb them, just enjoy them. If you are lucky enough to own property where the ephemeral ponds form in the spring, make every effort not to drain them. Ditches may breed mosquitoes, but they also breed frogs to eat them. If the mating pond of hundreds of years of generations of a frog species is drained, then the population is not likely to survive more than a few years, or until the adults die off. I live in Frostburg, Maryland, and there are more mosquitoes in my yard than I ever see near my house on the Cacapon, since there are so many things that eat them there. The bugs you see around your lights at night are not mosquitoes, since mosquitoes are not attracted to light, and that gives me an idea for another article. (Written by Don Robinson) New Editor(s) for Cacapon Currents The Cacapon Currents newsletter has previously been edited and constructed by Ms. Abby Chapple Walker. She has recently resigned from her position as board member (though she is still a member of the organization) to pursue other environmental issues with the Sierra Club. Abby is no stranger to hard work, and she and all the work she did will be missed by The Friends of the Cacapon River. Cacapon Currents is living on in the hands of Don Robinson (webmaster), writer Barbara Tufty and fisherman Eddie Bilezikian. All are board members of FCR, and none have experience at newsletter construction. Please bear with us as we find our way and try to fill Ms. Walker's big shoes. A print version of this may later become available, but for now the print version's future is uncertain. One thing is very clear. We can not do this without your help. If you have any ideas for a pertinent article, please send the information to dprobins@hereintown.net . Completely finished articles are welcomed, and color pictures are grand on the web. On a further note, Cacapon River resident Marjorie Harnest was not responsible for any of the runoff noted in a previous issue of Cacapon Currents. We are sorry for any mistaken perception from the article. The owner of the property in question has taken steps to remedy the situation. Certainly no harm was intended by him. It does point to a need for property owners to educate themselves about things we should and shouldn't do to preserve the river we all love so well.
