Winter wonderland – sparrows and warblers

Yesterday, as I walked through my yard, I was surprised to see groups of daffodils sticking up their heads; it seemed rather early to me but last year we had early signs of spring as well. It is a big contrast to our weather conditions less than a month ago, though. On the 17th of January, our town was surprised by 11-12 inches of beautiful, powdery snow.

  

  

 

While our southern area often has a couple instances of (light) snow and/or an ice storm in the winter, our climate is generally fairly mild and temperatures in the 50s and 60s Farenheit are not uncommon during winter. So the brief but heavy snowfall was quite an event; our streets were empty of traffic as everyone stayed home and watched the falling flakes.

Some people built snowmen, others went sledding and walking, and some of us spent hours filling our bird feeders and watching the birds. I also made an attempt to photograph some frozen bubbles, which was very challenging since it was windy during the entire winter weather event.

  

The snow began slowly melting a bit the next day, which made some of the icicles on the house elongate to a length of almost 3-4 feet, but it wasn’t until Friday and Saturday that the snow and ice really started disappearing.

My yard looked beautiful, but I spent time on the 17th repeatedly knocking snow off the bird feeders and heated birth bath so that the birds could reach the food and water.

  

   

Although I saw a couple squirrels and the white-tailed deer (Odocoileus virginianus) also came by, I didn’t see other mammals like chipmunks, raccoons, opossums. But I had 25 different bird species come by on Wednesday and Thursday; on Friday and Saturday, two more species came by. I’d like to share some snow day photos of them all in this and the next few blogs.

First up are the sparrows and warblers. The chipping sparrows (Spizella passerina) usually get their seed from the hanging feeders in the front and back yards but now they were looking everywhere for a bite to eat. I had strewn some seed on the ground and they began looking there.

One found a trove of food and another came by asking to be fed, a request the first sparrow accommodated quite sweetly.

 

 

The white-throated sparrows (Zonotrichia albicollis) have an opposite feeding strategy, usually feeding on the ground and occasionally venturing up to a feeder. They, too, searched under the snow for some food.

 

The pine warblers (Setophaga pinus) tend to be rather shy; only very rarely does a pair visit together. Mostly, one shows up at a time; their beautiful yellow color was really highlighted against the white background.

 

The pine warblers did have to brave a bad-tempered bird to get to the feeders. One of the six resident yellow-rumped warblers (Setophaga coronata) has become very territorial, chasing away some other yellow-rumped warblers, the ruby-crowned kinglets and the pine warbler – in other words, the birds his size or smaller. He allows a couple other yellow-rumps to feed peacefully and I think perhaps they are his family members so that he tolerates them. He didn’t stop the other small birds from coming around, however, as we’ll see in the next blog.

 

Rain drops, dewdrops and frost – Mother Nature’s adornments

rain drops IMG_8843© Maria de Bruyn resDewdrops in the early morning, raindrops during the day, and frost covering everything outdoors can be seen merely as various manifestations of heavenly water on earth, but another way of looking at them can be as nature’s jewels. When light and sunshine illuminate the drops and crystals, they lend an air of elegance and beauty to whatever they have covered.

When it rains, leaves and blooms may look uniformly slick with moisture but we often see them covered in rain drops. Have you ever wondered why the rain drops are of different sizes?

The US Geological Survey’s Water Science School reports that water vapor wraps around particles in the air (salt, smoke, dust) which are of different sizes; then when the drops begin falling to earth, they bump into other drops and merge. The drops that merge with more “neighbors” become larger. Rain drops suspended from branches and leaves are quite lovely.

Dew – water droplets on surfaces of objects and vegetation – forms when an exposed surface cools down by radiating its heat and the moisture in the atmosphere then condenses faster than it evaporates. It looks beautiful on flowers and other plants, such as these grasses, the Virginia meadow beauty (Rhexia virginica) and the Orange mahogany esperanza (Tecoma stans “Orange Mahogany”).

Some plants actually mimic dewdrops, like Tracey’s sundew.

On spider webs, water and ice droplets outline the architecture created by the arachnids, showing off the symmetry and beauty of the lines.

The webs of sheetweb dwarf spiders (Florinda coccinea), often not so visible in the grass, become quite noticeable when covered in dewdrops and then you can often spot the little red spider hanging underneath waiting for its prey.

In this case, the plant looked like a natural jewelry stand for strings of glass or diamond beads.

It was interesting for me to learn that the Indian Institute of Management Ahmedabad (IIMA) and the International Organisation for Dew Utilization (OPUR) created a dew harvesting system for a semi-arid area in India. Their condensers can collect more than 200 liters of dew each night from October through May and could provide an additional water source for people in arid coastal regions.

Leaves and flowers, like this coral honeysuckle (Lonicera sempervirens) can seem bedecked with glistening jewels when the ice crystals of frozen dewdrops adhere to their surfaces and edges.

frosty morning leaves IMG_7351©Maria de Bruyn Nat GeoFrost may appear to be translucent or crystal clear; when a mass of crystals are together, they look white in color because they scatter light in all directions. The ice crystals of wind frost (also known as advection frost) arise when a very cold wind blows over tree branches, leaves and flowers; they can form gorgeous borders on these surfaces.

Early morning can be a great time for nature walks – beautiful sunrises, brisk (or cooler) temperatures and awakening wildlife make for interesting viewing. And raindrops, dew and frost can add extra scenes of beauty for us to appreciate!
