One of the best ways to connect with nature is to monitor bird nest boxes. Regularly checking the contents of an active nest box lets you watch the whole breeding cycle unfold before your very eyes! It starts with nest building, progresses through egg laying and nestling rearing and then (hopefully) ends with the young birds successfully leaving the nest.

The Delaware Nature Society has a team of eager volunteers who monitor over two hundred boxes spread throughout several properties and every year brings more data and surprises. Our most common occupants are Tree Swallows, Eastern Bluebirds and House Wrens but most years we attract a few Carolina Chickadees, Carolina Wrens and Tufted Titmice. One year we had a White-breasted Nuthatch use one of our boxes – who knows what species might show up next?!

Opening this nest box revealed a Carolina Chickadee sitting tightly on a nest. In these cases we leave the bird alone and retreat.

Checking boxes lets you see for yourself the many differences between each species in the way their nests are built, the shape and color of their eggs, and the appearance of their nestlings, as well as the nesting quirks of different birds. Did you know for instance that House Wrens often add spider cocoons to their nest, probably because the spider hatchlings eat arthropod pests mixed in among the nest lining?

Our boxes remain in place year-round and provide winter refuges for both welcome and (slightly) unwelcome guests. Eastern Bluebirds roost in our boxes overnight during the winter, presumably to help them stay warm, and sometimes bundle together in the same box. Last winter one of our boxes at Coverdale Farm Preserve had an enlarged entrance hole and was filled with acorns from the huge old Red Oaks that line the driveway. This was probably a squirrel using the box to cache a supply of acorns to chomp on if a sudden snowfall made food hard to find.

Mice also like to spend the winter in our boxes so we have to bump them out to allow the birds to nest. Can you spot the two mice jumping out of the box?

We have been cleaning out our boxes to get them ready for spring and the birds are checking them out already so nesting isn’t far away! We can always use an extra person or two to help monitor nest boxes at Coverdale Farm or the Red Clay Reservation near Greenville, or Abbott’s Mill near Milford, so if you want to get involved just give us a call on (302) 239-2334. Boxes only need to be checked once a week and monitoring them makes a great excuse for talking a walk on a summer evening or weekend at these beautiful sites. All of our data are submitted to Cornell University’s ‘Nest Watch’ scheme so we are contributing to science as well as simply enjoying nature.

If you’d rather put up your own nest boxes why not join our upcoming program (April 27th at Ashland followed by a field trip to Coverdale on April 29th) to get advice on how to design and position boxes in order to attract nesting birds to your property? Having birds nest in a box you built yourself is a tremendously satisfying experience that may be repeated for many summers to come!

In these not-so-wintry days with temperatures in the high 60’s, you are the only creature fooled into thinking it is spring.  Plenty of plants, and an abundance of animals are responding as though it is April.  During a walk at Ashland today, with 68 degree heat, I noticed some things that weren’t showing themselves this time last year.  The most exciting show at Ashland right now is the emergence of Wood Frogs.  Get out to Ashland within the week if you want to catch the action.  As I write this, the sound of the male’s “quacking” is percolating through my open window along with a warm breeze.  Listen to the short audio clip of the Wood Frogs calling from a small pond next to the Ashland Nature Center.

Male Wood Frogs like this one are currently "quacking" away, in the hopes of attracting a female to join him in the water.

Wood Frogs lay clumps of eggs that will soak up water after they are laid.  The ones below my hand are newer than the ones on my hand.  Can you see the difference?

Once a male and female Wood Frog find each other, she will lay eggs such as these, and the male will fertilize them.

Although the American Bullfrog won't lay eggs until later in spring, I was surprised to see one surveying the scene at Ashland on this warm 1st day of March.

A walk along the floodplain at Ashland Nature Center revealed several plants beginning their growth cycle for the year.  Several are non-native, invasive plants, but others are native.  The warm weather is giving these plants an early start this year, but it isn’t completely unusual.

Snowdrops are an ornamental, non-native plant that is found in the wild sometimes. They are always the first sign of spring here at Ashland, and they are in full bloom currently.

Lesser Celandine is blooming along the Red Clay Creek at Ashland right now. Unfortunately, it is a non-native, invasive species that is devastating wildflower diversity along waterways in our area by smothering the native wildflowers.

The long, yellow male flowers of the American Hazelnut are much easier to see. This is always one of the signs that native plants are starting the new growth year, and it is fun to spot these shrubs in the woods right now, when they tend to blend in later on in the year.

One of the early signs of spring I have NOT noticed yet is the Groundhog.  My guess is that during this early warm spell, they have decided not to show their faces, after  predicting we would have six more weeks of winter.  WRONG!!

Finally, the insects are also out and about.  I have seen Anglewing butterflies, true flies, a dragonfly, and many smaller, unidentifiable forms buzzing around lately.  The prize in this category, however, goes to the inch-long larvae of one of our firefly species that we found crawling on Ash trees.  We found dozens of them, and watched as they scampered around the trunks, looking for smaller insect to eat.

This large Firefly larva was crawling around the trunks of trees on the floodplain. They must have recently emerged, since there were dozens of them. These insects will dine on smaller insects they can catch as they slink up the trunk.

The Teen Naturalists kicked off 2017 by orienteering at French Creek State Park in Berks County, PA. This 7,339 acre park was logged repeatedly to make charcoal for the Hopewell Furnace, which operated until the late 1800s. The land was sold to the government in the Great Depression, and managed similarly to the national parks at the time, with the Civilian Conservation Corps building recreational facilities in the park. Today the park land is owned by the State of Pennsylvania and the National Park Service maintains the historic furnace as the Hopewell Furnace National Historic Site. This park is the largest contiguous forest between New York City and Washington D.C., known for the variety of wildlife and recreational activities, including more than 35 miles of trails.

French Creek State Park is also home to a permanent orienteering course. Orienteering is a sport that combines navigational skills and racing. Participants use a highly detailed map and a compass to move from point to point, trying to complete the course in the least amount of time. We were not that competitive, but we did enjoy the challenge of navigating ourselves through the course around Hopewell Lake.

After a quick introduction, the Teens began to familiarize themselves with the compass, map, and map legend. Orienteering maps are incredibility detailed – roads, fences, trails, streams, hills, depressions, rocks, vegetation, etc. are accurately located. The Teens oriented themselves from our starting point in the parking lot to “control #1”. We set off in that direction, searching for a post with an orange and white square at the top.

Each post had the control number and letter code on the marker post placard. The letter code is recorded for competitive orienteering, to prove you made it to that location.

We recorded the letters in hopes that they spelled a word upon completion of the course, but they unfortunately did not. Photo by Carrie Scheick.

The misty rain and fog provided us with beautiful scenery in the woods. We saw and/or heard multiple species of birds including Mallard, Pileated Woodpecker, Belted Kingfisher, Downy Woodpecker, Hairy Woodpecker, Carolina Chickadee, White-breasted Nuthatch, Brown Creeper, and Eastern Bluebird. There was a variety of fungi including puffball fungus, polypore fungus, and witch’s butter fungus. A Northern Watersnake took advantage of the mild temperatures and came out to say hello to us at the dam.

For most of the Teens, this was their first experience orienteering. They all enjoyed the challenge, as it gave additional purpose to their hike and time outdoors. This outing was a great way to kick off the year!

Many visitors to Ashland Nature Center have been enjoying our newest attraction – a bird blind! The bird blind overlooks a cluster of bird feeders along Wildflower Brook and is the perfect place to view birds and other wildlife up close.

As long as you sit quietly you can watch dozens of birds come to the feeders, bathe in the brook, or just hang out in the trees nearby, and since they are so close you don’t even need binoculars. This makes blinds an excellent way to get children interested in nature since even youngsters can enjoy watching the birds going back and forth. Having said that, just a basic pair of binoculars lets you see a lot more details of the different birds like their beak shapes and feather colors so try borrowing a pair from the visitor center if you don’t have your own. Blinds are also excellent opportunities for photographers as the nearness of the birds means you don’t need an expensive camera with a super-zoom lens – all you need is patience! If you’re lucky you may also see a Red Squirrel visiting from the nearby hemlocks or perhaps a cute little Eastern Chipmunk, both of which are uncommon mammals in the Piedmont. Imagine how memorable it would be this winter to watch a Red Squirrel searching for food in the snow while you’re sheltered inside the blind!

The blind looks out over several types of feeders stocked with different seed mixes and suet cakes which each attract different species of birds. This variety adds a fascinating insight into how different birds feed – some birds like House Finches and Goldfinches perch happily at the feeders and chomp away until they are done while others like Chickadees and Tufted Titmice zoom in and grab one seed before carrying it away to a nearby tree and hammering it open. Woodpeckers and Nuthatches have a remarkable ability to hang upside down on suet cake cages and peck away at the contents while bigger birds like Blue Jays can’t perch very well and prefer to grab whole nuts from table-top feeders.

Visiting Ashland’s bird blind will inspire you to buy your own bird feeder or give one to somebody else (they make great Christmas presents for anyone regardless of where they live in the city or countryside). Just hang them from a tree or pole at least a meter from a window (to minimize window strikes) and see which birds you attract. It is probably best to fill them with black oil sunflower seeds since this will attract many birds although some species prefer millet or nyger (thistle). Wild Birds Unlimited in Hockessin is a great local specialty store for bird food and feeders though most supermarkets also sell seed and suet cakes.

For me, watching birds at feeders is both entertaining and soothing and a bird blind stocked with several feeders is the sum of human happiness, as well as a relaxing way to connect people of all ages with nature. Next time you have a free hour or so come and hang out at the Ashland bird blind and see what I mean!
