Love is definitely in the air. Has been for some time, but in the last few days, I’m noticing a lot of telltale signs that animals are seeking animals. It started a few weeks ago with the woodfrogs mentioned in the previous post. Now, other frogs and some birds are catching the love bug.

On a recent frog slog with a friend (yes, that is what I do on Friday nights, don’t laugh), we were searching for an elusive, unconfirmed endangered species in Lower Makefield Township called the Northern Leopard Frog. They often share habitat with other amphibians such as bullfrogs, green frogs, pickerel frogs and spring peepers. Slogging through the water and mud in hip waders on a warm spring evening, the peeper singing was so loud, it literally hurt my ears. These little frogs are only the size of a man’s thumb nail, but their calls can be heard about a mile away. You’d think since they are so loud, they’d be easy to find. Not so. They are extremely hard to spot and they are often not at the water’s edge where you’d expect, but in the shrubs.
The males call a high pitched whistle to advertise they are a SPM (Single Peeper Male) ISO SPF. If another SPM comes calling, they add a trill to their whistle and a territory dispute ensues. The more dominant male wins the spot and can wait for a female to come by.

 

If a male and female do “hook up” she deposits eggs and he fertilizes them as they are extruded. The tiny eggs are laid singly and are about as big as of the head of a pin.

 

 

 

 

Some animals have already done their hooking up and are done for a while. My friends’ neighbor just brought me a baby turtle to be identified. Her son had found it walking around their back yard. Since I’m doing a turtle program in a few weeks, he was kind enough to let me hold on to it until then. This baby painted turtle is no larger than a quarter and hatched from an egg laid on land.

 

Other animals looking for love are birds. I’ve been hearing woodpeckers drum against trees for several weeks now. This is the time of year I get calls from friends about dumb woodpeckers pecking on aluminum siding or against the gutters. These amorous males aren’t looking for insects in your gutters. They peck against these things because they make a good noise. Mostly though, I’ve been hearing their drumming against hollow trees. The sound resonates and not only advertises a good territory to ward off competing males, but the girls like it too.

Over the next several weeks, you’ll notice lots of birds singing. Male birds sing to advertise themselves to the females and posture to other males. Get out with your kids and count how many different bird sounds you can hear. Once you get better at identifying a particular song, see if you can hear a competing male a few yards away. You’ll notice they actually “talk” to each other. You may begin to determine how far apart each territory is for each bird. Enjoy nature.

It may not feel much like spring, and the calendar may say it is still a 5 days away, but spring has definitely sprung around here. Spring can be very subtle, and you need to be cued into the clues, but, if you look and listen carefully, you will soon discover that the seasons have changed.

On a recent trip to the bank, I noticed the branches of the silver maple lining the road had a distinct fuzzy appearance. I pulled over and discovered they were in fact blooming. Many people don’t realize trees bloom unless they are obvious like dogwoods, but maple trees are in full bloom now.

 

 

Another tip that spring is here has actually finished already. Just 5 days ago, the wood frogs were calling in the vernal pools of Five Mile Woods. With the first spring rain, the males make their way to these temporary pools and start calling. The females follow shortly after. You may have mistaken their calls for quacking ducks, but they are small woodland frogs that wake, call, mate, lay eggs and leave all within a two week period.

 

 

Thousands of jelly-like eggs are laid by the females while the male clasps her from behind and fertilizes the eggs as they come out. Also calling, and they will continue to do so for several weeks, are the spring peepers. These tiny tree frogs are no larger than a man’s thumb nail, but their loud whistling peep can be heard up to a mile away.

 

The last amphibian to wake from spring is a silent one. Along with the woodfrogs, the spotted salamander remains underground most of the winter. With the first “warm” spring rains, they migrate, sometimes in mass, to vernal pools. Males congregate first, followed by the females. Their courtship, though brief is very interesting, but hasn’t happened yet, so I’ll save it for another post.

Get outside and discover spring before it is too late.

I’ve been trying to put my finger on it for years now. What exactly is that smell? Last Sunday, it was a warm day, but there wasn’t that smell; the smell of spring. This morning, I went out to drive one of my sons to school and there was something in the air. It just smelled like spring. The birds must have felt it too. A Northern Cardinal was singing his song “popcorn, peanuts, chiiiiiippps” instead of calling. The House Finches were singing too. On my way to work in Princeton, I had the sun roof open and I heard the Pe-ter, pe-ter, pe-ter of the Tufted Titmouse song.

Skunk cabbage Symplocarpus foetidus is blooming along the stream. It has such a high metabolic rate, it actually melts the snow and ice around itself. No need for that today.
While on a walk with a group of preschoolers this morning, a honey bee was out looking for early bloomers. I don’t think she found any, but I sure enjoyed seeing her out.
I hope you got out to enjoy and smell the day. I know it won’t last. They’re calling for snow on Saturday, but it is a nice tease knowing nature still remembers how to be warm.

On Wednesday morning, I dropped the boys at their respective schools and headed to one of my favorite places, Bowman’s Hill Wildflower Preserve. I knew the perfect snow that fell the night before would soon begin to melt and I wanted to get to the Preserve to photograph the wintry scenes. I wasn’t disappointed. There was about 5″ of it and was the perfect consistency. Not too heavy, not too light, just right to cling to branches, boughs and pine cones. The sweet gums that persisted on the trees looked like they had little dunce caps perched on the top of each one.

The sun was just coming over Bowman’s Hill and already, by 9:30, it was starting to melt the snow. Huge clumps of soft powder were falling from branches. It was like having a snowball fight with an invisible giant who could pelt you from above without knowing where it was coming from.

It was so quiet at first, but as I walked, the woods seemed to awaken. Canada geese flew over, their huge wings and their incessant honking were audible in the quiet of a winter morning. I watched a gray squirrel scurry down a tree, go directly to a particular spot, dig up an acorn, scurry back up and eat it. I’ve read gray squirrels only find about 1% of the nuts they bury, but they do sniff out other squirrels’ stashes.

The sky was so clear, it almost hurt my eyes to look up. I saw a flock of snow geese flying over head and I couldn’t change to my zoom lens fast enough, so I just took a shot of them with my regular lens. Tiny white specks in a crystal blue sky.

Pidcock Creek was frozen, but I could hear and see the water running under the ice. In a tree limb hanging above the creek was a bald-faced hornet’s nest. Long since abandoned, it held a pile of snow on top like a hat.

The time slipped by really fast, and I found myself rushing to get back for an 11am appointment. I hope all of you took the time to get out and enjoy the snow. Even if just for a few minutes. Snow reveals secrets you never thought could be right around the corner.

Here is an interesting opinion piece in the NYTimes about honey bees and a strategy to possibly prevent Colony Collapse Disorder.
