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.

Spring is in full bloom here at Abbott’s Mill Nature Center!  Flowers are blooming, bees are buzzing, birds are chirping, frogs are croaking, and fish are biting.  While spring brings plenty of excitement for nature enthusiasts of all passions, there are a few birds that have arrived here at Abbott’s Mill Nature Center that we hold near and dear to our heart.

The first “birds of spring” that arrived were the largest member of the swallow family, Purple Martins. These birds will spend the winter in South America and then migrate all over North America during their mating season. Adult females have a lighter breast than the adult males, and both take part in building nests and feeding young.

Populations that migrate to the Eastern United States are completely dependent on man-made structures, like the ones pictured above, for nesting. Researchers theorize that this is due to conditioning over many generations, as early writings from European settlers note that Native Americans placed whitened gourds near their crops and dwellings to attract Purple Martins in order to take advantage of their voracious appetite for insects.

Not long after the Purple Martins arrived, their cousins and the most common member of the swallow family, Barn Swallows announced their arrival with flashes of glossy blue wings and their chitter-chattery calls. They winter in Central and South America and then make their way back to North America during their mating season. Barn Swallows are also largely dependent on man-made structures to build their nest upon, which they make out of a mixture of mud and grass. In the communities of Tangier and Smith Island, located in the heart of the Chesapeake Bay, watermen and their families affectionately call these birds “Shanty Birds”, due to the multitude of nests that are built each spring under their crab shanties that sit just above the water on pilings.

Later in the year, the Barn Swallows will be raising their families in mud cup nests attached to the barn, mill, or house here at Abbott's Mill.  Photo by Joe Sebastiani

Barn Swallows have the deepest forked tail of the swallow family, and you can catch a glimpse the bright white dots that highlight their tail when it is fully fanned out. Their swooping and diving through the air isn’t for naught, as all members of the swallow family are aerial insectivores, meaning they dine solely on flying insects. The adult male has bolder colorings and a darker throat than the adult female, and soon we will be seeing the pale-yellow beaks of their young.

Finally, just this past week we spotted the first pair of Ruby-throated Hummingbirds fluttering about in the native plant demonstration garden just in front of our Visitor Center. The only hummingbird that breeds in the Eastern United States, this short-footed, fast-flapping bird spends its winters in Central America, sometimes crossing the Gulf of Mexico during its migration. Adult males, like the one pictured below, are easily identified by their eye-catching, iridescent throat. All hummingbirds are uniquely adapted to feeding on the nectar of flowers with elongated beaks and wings that flap up to 53 times per second. Not only are they the smallest species of bird known, but they are also the only species that can both fly backwards and hover in place.

If you have a hummingbird feeder at home, making your own “nectar” is an easy process. Start by combining mixture of 4 parts water to 1 part sugar in a large pot. Bring the mixture to a boil, with occasional stirring to aid the dissolving process, and then let it cool. Don’t add food coloring or honey to your nectar mixture. It may be harmful to them, and all they want is sugar-water.  Clean your feeder once a week with a weak bleach and water solution to prevent and kill mold.  While hummingbirds will also dine on nature’s nectar, keeping your feeder out until their latest migration period, usually late September to early October, will help ensure your viewing pleasure and a final dose of energy for their long flight south. Additionally, research has found that these fascinating birds even remember where you put your feeder from year to year, so make sure to place your feeder in an optimal viewing area for you and your family and mark the spot when you take it down for the winter.
