Bird Feeding Series: House Wrens

Wren: loud and friendly
Of the estimated fifteen or so different species that I will likely cover in this series, I've opted to start with the Wren (pictured left).  From my own perspective, the wren has been the most interactive of the many bird species that I've encountered in my short duration as an amateur bird observer.  By interaction, I mean to say that this species - for whatever reason - has approached me throughout different seasons of the year (including when my feeders are not up and running) coming in unusually close proximity, and almost as if to communicate - looked directly at me and sung up a storm.  Of course, its understood that this is merely an entertaining illusion since birds of the native variety do not engage humans socially. 

Most the bird species that I encounter are extremely fearful of humans, and tend to make a bee line for the woods when I show up to fill my feeders.  However, the wren seems to stay within four or five feet to monitor my activity.  And chirps aways at me as I pour the seed. 

In summer, if I hear a bird singing right outside of my window at 5 am, its usually a wren.  Opening the window shade doesn't seem to scare him off or deter him, he just keeps on whirling and chirping to its heart's content.  Sadly, their curiosity can also be their undoing.  Last year, a wren must have followed me into the garage one evening, as I found one expired the following morning inside the garage near the house entry door.  Obviously, this was a sad moment, but its given me pause to watch out for birds seeking refuge in my garage during cold weather.  Two days ago, and in the evening hours, I opened the garage doors to take out the trash, and another wren must have snuck in during that three minute period.  Luckily I was able to see him sitting up atop of the garage door chassis, and I reopened the door and out he flew.  This has not happened with any other species except the wren.

Wrens Nesting Habits

Wrens build nests just about anywhere convenient; they seem to adapt to a variety of locations which include marshland, wooded areas, backyards, and even fields.  Strangely, their nest are usually built five to ten feet from ground.  However, in my yard, I've had wrens build their next in a woodpile just inside the woodland area that is only 3 feet high.  And they'll let you know if you come to close!

Most websites claim that wrens are extremely territorial and will defend an area up to an acre.  But this must be only for the purpose of nesting, because I often see a number of wrens feeding simultaneously at the feeders, and around the yard.   I do know that they spend plenty of time filling my birdhouses with twigs and sticks in order to create what is known as a dummy nest, so that other bird species do not nest in their territory.  I was particularly dismayed by this when attempting to attract bluebirds to my yard.  Within days of putting up the boxes, I found them filled with twigs.  Emptying them usually results in them being refilled with twigs in a few days.

I also know Wrens are responsible for having destroyed a thriving chickadee nest in my yard last year.  They destroyed the eggs, and once again filled the birdhouse with twigs and sticks.  For this reason alone, there are dozens of sites devoted to ridding your yard of  Wrens, I'd rather not take to destroying any existing nests and simply hope for the best.

Wren eating habits

Wrens spend their summer feeding on spiders, and insects.  During the winter they follow suit with most bird species and consume seeds as their primary diet.  I find that they particularly frequent one of my feeders which contains nuts and dried fruit.  But they also feed on sunflower, and eat at the seeded-suet station. They also appear to be ground feeders, as they spend a lot of time scooping up whatever falls from the multi-seed feeders .

Wrens don't appear to be overly aggressive at the feeders, but they also don't move off when antagonized by other birds trying to squeeze out competitors. 

It's not difficult to attract wrens to your feeding station.  They've been regular visitors to my station over the past four years, and its likely that because they don't migrate south, that its likely that the same birds are likely around my yard year round. 

One last note, I've had some difficulty determining the precise species of wren that I've been encountering.  The books and websites I've consulted seem to have inaccurate titles for a variety of wren species pictured - the Carolina Wren, House Wren, Marsh Wren, in addition to other subspecies - are quite different from description to description shown which has made my ability to correctly identify them more complicated.  The picture above was borrowed, but closely resembles the bird appearing at my stations.  I will be uploading my pictures over the next day or.   Any thoughts about what specific species this may be would be helpful.   Once again, I'm located in Connecticut.

Bird Feeding Series

On a snowy winter's day here in New England, I thought I'd start my first entry on my series about Bird Feeding and some of the wonderful species that frequent my feeder stations.   There is something about these flying creatures that makes you pause and think about the complexity of nature.  Birds are interwoven into our daily background, and often go unnoticed by most people as they go about their day.  But for those of us more in tune with nature and our environment, our feathered friends serve as a reminder of the magic of creation.

From my own experience feeding and watching birds, I've come to the conclusion that bird species are often quite different from each other in more ways then their size and natural beauty.  The are distinct in their food and feeding preferences, and in their nesting requirements and habitats, and I dare say - even their personalities, if you will.  Obviously, birds operate on instinct, and not complex thought patterns which makes their behavior by species repetitive and predictable.

I feed the birds for the purpose of enhancing the beauty of my yard's natural landscape and the personal enjoyment that it brings me.  It's also a small way to assist nature in its continuous natural seasonal cycle.  And I would say that the large number of humans engaged in feeding birds, particularly in the winter months, does in fact assist nature by contributing to the survival of some species which must deal with the brutal realities of New England winters.  That being said, I probably get more out of it than I give.  There are hundreds of man-made food sources found in the form of neighborhood feeding stations that abound.  But there are thousands more natural food sources for birds found in the woods, and fields of my region which provide birds ample nutrition.  I'd like to think that my contribution, however small, makes a difference to at least my regular visitors.

I have a few different feeding stations which are filled with different types of seeds and foods for the purpose of attracting the most diverse number species of birds possible.  And I've found through trial and error that feeder types, seed types, and even seed brands impact the population at your feeders.  So as I indicated earlier, birds may operate on instinct, but they aren't stupid - and they can be rather picky creatures.  And since I'm not the only game in town, they can afford to be choosy.

I will get into greater detail in future entries about my feeders, but at least for now, I will say that I cover the basics.  In winter, I offer mixed seed, suet, sunflower, and nyjer (thistle).  And my most regular visitors are chickadees, titmice, nuthatches, sparrows, finches, woodpeckers, mourning doves, wrens, sapsuckers, and lot of little juncos.  I also get the occasional blue jay, cardinal, and varieties of blackbirds - but these visits are much rarer than they have been in the past.  All in all, its a good assortment of species, and they tend to often come in waves, likely moving from feeding station to feeding station across the neighborhood.  

Some of these species get along quite well with each other, while others are a downright nuisance to other species and to each other.  I hope to shed some light on these characteristics, and also hope a few people in the birding, birdwatching, birdfeeding community might chime in with their experiences and thoughts.  I'm by no means an expert on birds and birdfeeding, so I hope to learn as much as I impart.  And perhaps some of my limited knowledge might encourage those not feeding the birds to hang a small feeder and enjoy the beauty of some of nature's most beautiful creatures.

Looking forward to the next entry!

Monday January 3 - Tuesday January 4: Quadrantid Meteor Showers

Monday night into Tuesday morning you can expect our first Astronomical event of the year - the Quadrantid Meteor Showers.  For those of us on the East Coast of the United States, the viewing time is expected to be good Monday between 6 pm and midnight (with the peak occurring at 8 pm EST).

As I've previously posted, for those of us in the Northeastern United States were quite unlucky for the two astronomical events that occurred in December (The Geminids and the total lunar eclipse) due to severe cloud cover.  According to weather reports (as of this posting) it is going to be clear on Monday night with a clouds lingering in late with a chance of flurries - we are hoping that the forecast will remain clear, and that cloud cover occurs after midnight. 

The Quadrantid Showers are highly anticipated because are expected to see 100 meteors per hour because the meteors radiate low on the horizon. The shower will likely have several bursts of meteors occurring in rapid succession with lulls that could last as long as 7 to 10 minutes in length.  These showers are generally seen as bluish flashes with long grey tails, although they can be green and red if they interact with certain gases in the atmosphere.

Also, note that viewing location will be important since the meteors will be fairly low to the horizon (note the illustration above).  Constellations points are the end of the Big Dipper's Handle (Ursa Major) and the Head of Draco the Dragon (the two peering eyes in the sky).

The Quads were first recorded as being viewed by Italian Astronomer Antonio Brucalassi on January 2, 1825.  According to The Day Newspaper: "The first sign that the activity was annual came in 1839, when Adolphe Quetelet of the Brussels Observatory in Belgium and astronomer Edward C. Herrick of Connecticut independently suggested it."

Here is a link to video of the 2010 Quadrantid Meteor Shower.

Dress warmly and happy viewing!
