Hello again, River Bend friends! As you have probably noticed, Spring has sprung and we are really enjoying all the changes that are happening here. Many snakes and frogs are waking from their winter naps – if you walk by Prairie Pond or Upper Pond, you can hear the frogs croaking! There are so many new birds out and about, and they are all singing at the top of their lungs and hurrying to make nests in the forest, prairie, and pond alike. We have even seen Turkey Vultures, and though they neglect to sing, they are another sign that the warm weather is back.
Spring is a wonderful time to look up and take notes of the phenology of our area. Phenology is the study of the timing of natural events from year to year, and is really cool to discover – here at River Bend, we have a monthly Phenology board, where our visitors can come and write what they saw while out on the trails, and then this gets recorded and we can compare to several previous years. We also have a great book written by our founder, Orwin Rustad, which is a recording of 50 years of natural events!
To give you an example of phenology, I’ll tell you what his book says about the timing of Turkey Vulture spring arrivals: over 12 years of recording their comings and goings, the earliest they arrived was March 12th, and the latest was May 30th! Their average though is April 14th-17th, so they are a bit early this year.
One of the reasons phenology is important is that it helps us note changes through time. The reason I chose to look up the Turkey Vulture (other than the fact that they are amazing birds!) was that they were not very common birds in this area 50 and 60 years ago. Most of their sightings started in the 80’s and 90’s, perhaps indicating that Turkey Vultures were expanding their ranges in that time frame to include this area! If you are ever in the interpretive center and want to know more about the natural history of this area, check out this interesting book.
You can also take advantage of the gorgeous weather forecast and come for a hike and see the spring changes for yourself. Just today, school groups spotted Garter Snakes over by Honor Point, a Bald Eagle over the Strait River, and saw the turtles that have come out at Turtle Pond too! There are also tons of frogs and birds to see and listen to, so come to River Bend, explore, and then come contribute to our Phenology board.
After hearing the frogs start up around town or here at River Bend, are you curious to learn more? Then come to our awesome program on Saturday, April 15th: Fabulous Frogs! Hop on over to learn about what’s jumping around River Bend’s ponds – We’ll be learning about what makes Frogs so unique, creating our own frog chorus, as well as meeting our two froggy Animal Ambassadors! The program fee is just $5/person, $15/family ($3/member, $10/member family), and it runs from 10-1130, so come make a day of it here at River Bend – see the program and then go for your own hike!
Hope to see you soon!
