I few posts ago I mentioned Nest Watch, a nest monitoring
program with which I’ve recently become involved. I’ve been assign to monitor
four boxes installed at the school campus a few miles up the road from my condo
in Union, KY. Since I now have three nests and a total of 16 eggs distributed
among those nests, I thought I would follow up with more information on the program.
I’m very excited to see the use of the man-made bird boxes and am hopeful that soon
there will be baby birds flying about and twittering songs in our neighborhood
trees.
According to the organization’s website (
http://nestwatch.org/about/overview/),
the program is designed to “track status and trends in the reproductive biology
of birds, including when nesting occurs, number of eggs laid, how many eggs
hatch, and how many hatchlings survive. Our database is intended to be used to
study the current condition of breeding bird populations and how they may be
changing over time as a result of climate change, habitat degradation and loss,
expansion of urban areas, and the introduction of non-native plants and
animals.”
The location of the four boxes that I monitor seems totally
in line with the organization’s intend. The school campus is huge, includes
elementary, middle, and high school, plus all the necessary venues such as gymnasiums,
football and baseball fields, a quarter mile track, and several basketball
courts… not to mention all of the parking lots and maintenance buildings. The neighborhood
of these schools is all suburban-sprawl. Where now there is housing enough for thousands
of families, ten years ago used to be nothing more than cow pastures and farms.
I know the population is growing, I know growth is good for the economy (?),
but how is all of the new construction effecting the habitat as a whole? Four
bird boxes cannot possibly make up for the vast amount of trees lost in all of
the construction. However, in the county’s defense, they have tried to leave
some green spaces and develop a more sustainable community then many of the
neighborhoods build a few decades ago.
So, in comes Nest Watch to track data. I’m sure they know
bird population will decline as human population grows, but the first step is
bringing attention to the situation. Installing these boxes and getting people
like me to go out twice a week and look at them is one way of doing just that.
What they do with the data is yet to be seen.
Here are four Bluebird eggs. This is actually a second
attempt for my Bluebirds. When I first started monitoring the boxes, I had a
nest with four Bluebirds eggs and a few days later they were gone! The nest was
still there, I didn’t see any broken eggs or evidence of a critter getting into
the box; the eggs were just gone. At first I suspected a hooligan kid from one
of schools, but the fact that the nest was still there lead me to think
otherwise. If a kid was going to take the eggs, don’t you think he would have
taken the nest too, even if for no other reason than at have a safe way of
carrying the eggs during his get-away? So, the only other conclusion I can come
to was that the eggs fell victim to a snake. Though, that is also seems unlikely,
since the bird box is on a post with a plastic baffle around it, designed
specifically to stop animals and snakes from crawling into them. I’ll keep my
eye out and see what happens to these four eggs. One last note on the
Bluebirds, I have yet to see the parents. I’m told the Bluebirds are very timid
and will not hang around the boxes when there are people around. I am anxious
to actually see a Bluebird; I only know what they look like through pictures in
my guide book.
These are Tree Swallow eggs. Two of my boxes have Tree
Swallow nests with six eggs in each. These birds are very active and assertive
around their nests. I’ve seen both parents at the boxes on my visits. Usually
one is sitting on top of the box while the other in inside the box. They are
beautiful birds. They have an iridescent blue head and back with a white throat
and belly. The females have a browner tone then blue, but honestly, they fly about
so fast that it is hard to tell the male from the female. Only when they land and
turn their back to me can I actually tell the difference.
On my first visit to the boxes I got to watch the birds
collect feathers for their nest. I was able to find a few feathers in the field,
so I threw them up, into the wind, and watched as the bird swooped over to
catch the feather and take it into the box. It seemed like they would play with
the feather for a while before carrying it to the nest. They would fly real
high and drop the feather, then swoop around and catch it. They did this
several times before taking it to the box. Maybe that’s their way of deciding
if it was a good feather or not.
The birds were a bit more aggressive on my last visit to the
box so I think the eggs might be close to hatching. As I was walking toward the
box, the bird that was perched on top flew up and circled overhead and another bird
flew out of the box. I opened the box, peeked in, snapped a picture, closed it
up quickly, and took a couple of steps back. As soon as I backed away the bird
overhead buzzed me a couple of times, not coming too close to scare me, but
close enough that I knew to stay back. Then the other one flew right back into
the box. I’m told that if we’re quick, we won’t disturb the process, but I felt
a little bad about scaring them away from the nest like I did. Next time I may
have baby bird pictures!
Before I close this post, I need to make a quick comment,
who says growth is good??? The population needs to stop growing and stop
expanding into undeveloped land. Why are so many people having so many kids???
If every female just had one child, just one, maybe the planet could support
the population a hundred years from now. I know, I know, I’m well on my way to
being a grumpy old lady who enjoys the company of nature more than of people.
Side note – noise neighbor had a long conversation on his
cell phone while sitting on his balcony, and he talked so loud, that I could hear
him from inside of my condo… with the windows closed… and the TV on... I
actually went for a walk around the neighborhood because I got sick of
listening to him. Not only is he driving me off my own balcony, but now he is
driving me out of my condo.
