The Brandywine Valley Eagle












A view of the Brandywine and Joe Pye Weed with tiger swallowtails at the Brandywine River Museum




















On Sunday my daughter and her boyfriend took my wife and me to the Brandywine River Museum. The museum is built onto an old mill. Two of the restaurant walls are floor to ceiling windows with a view of the Brandywine.

After breakfast we toured the 3 story museum exhibits wearing our little stickers that showed we had arrived early on Sunday morning when admission is free. The occasion was my 70th birthday.

I enjoyed the N C Wyeth paintings; paintings of other American artists and some really cool weathervanes on exhibit.

The highlight of the day was unexpected. On our way back to Coatesville we rode on narrow Chester County roads that mostly followed creek valleys.  My daughter said, “Is that a hawk?” I saw a flash of white tail. At first I thought, Northern Harrier. But the entire tail was white. I shouted, “It’s an eagle”.

American bald eagle was flying less than 100 feet away about 50 feet above the ground. She or he flew in about the same direction as our car for several minutes.

I had only seen photos or viewed bald eagles downstream of Conowingo Dam on the Susquehanna River. At the Conowingo site he eagles are out in the river quite a distance away. This was up close. We didn’t need binoculars. It was an elegant bird with dark brown body and wings and brilliant white head and tail feathers 


I doubt that this fierce and regal king of the sky or for that matter the small birds harnessing him thought much of us poor earthbound creatures cramped in a machine following a macadam path; but that eagle made my day.

Are mosquitoes making your backyard cookouts itchy? Try tree swallows & bluebirds.

Tree swallows take flying insects on the wing. Once the tree swallows come back to our house daytime mosquitoes disappear from the our yard.


A nesting box designed for bluebirds will also accommodate tree swallows. They are easy to find or if you have the skills you can make your own.


I use metal wire fence posts to mount the nesting boxes. Predators (mostly squirrels) can’t climb them easily.  If they can get to the nest box squirrels will chew at the entrance hole so they can get inside.

Bluebirds require more territory for nesting. Their boxes need to be about 60 feet or more from each other. However bluebirds and tree swallows will tolerate each other so put up nest boxes in pairs of two a few feet apart. It’s very important to put the boxes at least 10 feet from cover that can hide a predator.

This is how my boxes are arranged in the yard.





As you can see from the photos cats also can’t climb the metal poles. She only tried this one time.

Tree swallows use aerial tactics when driving off cats. One will come from behind and get the cat’s attention while a second, or sometimes third bird swoops down and pecks the cat’s head.  Now my cats avoid the tree swallows air space and hide under the porch furniture.

Check out the video below. Sorry for the shaky camera, it’s just an iPhone. You can see the little tree swallow poking his head out at the end for just a second.



It’s almost time for the swallows to fly south. But blue birds nest a second or even a third time.
