Plastic Pollution Awareness and Action Events in Jamestown – September 27

Plastic Pollution has become one of the greatest issues of our time; we’ve all seen the heartbreaking images of seabirds entangled in six pack rings, beached whales with bellies full of debris, and that video of the sea turtle with a plastic straw stuck in its nostril! Feel like you need to get out and DO something to protect our great outdoors and environment? Let’s do something together! The third week of September marks the first-ever National Nature Cleanup Week! Join some of the Jamestown area’s environmental ambassadors for one or both of the following programs on Friday,...

RTPI Begins New Plastic Pollution Research Initiative

Plastics have been around in their current form for decades, and estimates suggest that more than 8 billion metric tons have been created since large-scale production of plastic started in the 1950s. The vast majority of plastic that has been created is still in existence today – resting in landfills or floating around the planet’s waterways as litter. Plastics do not biodegrade, they photodegrade. This means that they don’t readily break down into their constituent materials, they simply break down into smaller and smaller particles. This aspect of their chemistry is creating cause for...

American Redstart Changing into Fall Plumage

American Redstart Changing into Fall Plumage

Many of our migratory birds are on their second or third brood for the season already and slowly are starting to prepare for their journey south. Most flashy warblers molt out of their brightly colored breeding plumage in the next few weeks and will start migration once all flight feathers are grown in to the point that they can safely sustain their long journey. Although we have not quite reached Roger Tory Peterson’s notorious “Confusing Fall Warblers” level of alternate plumage yet, the first signs are here. Even though this male American Redstart still displays its characteristic black...

The Great Spangled Fritillary!

The Great Spangled Fritillary (Speyeria cybele) and other native butterflies provide added splashes of color on summer days as they flit about our flower gardens, parks and roadsides. Butterflies don’t need much to thrive in our immediate vicinity. As long as you take extra care to plant native flowering plants that provide healthy foods for these animals (rather than non-native ornamental plants that don’t offer such benefits to our insects) and don’t spray pesticides, butterflies will be there to brighten your day (and pollinate your other flowers and veggies)!

Bullfrog Metamorph

Bullfrog Metamorph

It’s the time of year that local green frogs and bull frogs are leaving their watery confines to try a life on land. These large frogs breed only in permanent bodies of water, because they spend several years as a tadpole before metamorphosis. Unlike our vernal pool species, which breed earlier and are leaving their temporary pools before they dry, these species rely on permanent water that allows their tadpoles to overwinter – sometimes several times, depending on latitude. Want to learn more about the frogs in your neighborhood? There are Peterson Field Guides for that thanks to Roger Tory...
