Did rain dampen your plans for Earth Day?

No problem.

You can join the CRC’s 15th Annual Streams Cleanup.

Volunteers will meet to pitch in and clean up the creeksides on Saturday, May 5,  from 9 to 11:30 am.

Just choose one of several meeting sites in the Chester, Ridley, and Crum watersheds.

Then register to attend.

Sites include two spots along Little Crum Creek:  one upstream at Little Crum Creek Park in Swarthmore and one downstream at Ridley Park Lake.

Free t-shirt and picnic following cleanup.

After all, it’s always an Earth day, right?


Going on three springs now, our exploration of Little Crum Creek has been adding up to a fair catalogue of life along the water.

All along, I’ve been looking forward to creating a page where visitors can easily browse lists of flowers, trees, birds, insects, and everything else we’ve found.

Now, on the brand new Browse page, you’ll find several lists arranged for easy reference and identification.

Just click on any topic to see all posts that have featured what you want to see.

Browse potential will grow with every new post to the Home page.

Hope you find it as useful as I do!

Try counting birds …

in the Great Backyard Bird Count, Feb. 18-21.

It’s simple: 

Take 15 mins, count the birds you can identify, and submit the numbers online. 

If new to this, you might be surprised at how easily you can learn to identify the most common birds where you live.

The GBBC website has everything you’ll need.

Especially helpful are some identification tools like the “Tricky IDs” page and the option to enter your location to see a regional checklist of birds.

Use that checklist to see pictures, read behaviors, and hear songs at the Cornell Lab of Ornithology, a popular place to research birds.

Even if not participating, the GBBC has a lot of great information for getting to know our neighbors.

In town or city, nature is always on the wing out our windows.

And at least a small part of it will be counted along Little Crum Creek.
