Firsts and Lasts

A Rabbit Pond Exploration

Guest Post by Sabrina Appleby ’17

Last week in my Ornithology class, Mr. Cone split us up into groups and sent us on different missions. My groups’ task was to venture down to Rabbit Pond and record the number and condition of birds that are occupying the bird houses set up around the pond. These “houses” are similar to your typical bird house, and there are eight of them surrounding the pond. Ironically, I never noticed them until that day!

We had a spread sheet that asked whether or not there was a nest in each of the eight houses, if there were eggs present, and what kind of nest it was. Out of the eight that my group checked, we found four nests, one of which contained four small eggs. Every nest we found was a house wren’s. Very easy to identify, these nests are made up almost entirely of sticks.

Unfortunately, we did not actually see any house wrens in the area, but here is a picture for reference.

During our adventure, we had the great fortune to see three sets of parents and their baby geese wandering around the outskirts of the pond. Now I know these little ones are famous by now in the Science Department, but I felt it was worth mentioning again. The baby geese, just like we learn, followed their respective mothers’ every move. Despite geese’s typically friendly nature, these mothers were especially defensive. With each step that we took toward the family, the mother was quick to hiss back at us. Needless to say, we kept our distance!

In addition to our adventure down to Rabbit Pond, my class had the opportunity to see one of Audubon’s Birds of America copy in the Addison. Known as his “double elephant pholios,” Audubon’s giant prints were incredible! This massive book contains hundreds of birds, reproduced from his original work by the use of a copper plate and a printing press. Did you know this book, which is worth a lot of money, was once on display in the library? Good thing the Addison decided to take it in, as many of the edges of the book had been damaged by students. Pictured below is one of Mr. Cone’s favorite Audubon prints:

Here comes the hard part. Given this is my last post of the term, I wanted to thank all of my readers for following my journey through this class. It’s been a lot of fun to write for the PA Natural Sciences blog and learn more and more about birds. I want to give a special thank you to Mr. Cone for teaching such a great class. You will be missed at Andover, but we are excited to see your next adventure. Happy last week of class, and happy summer! ❤

With admiration, Sabrina Appleby

Home is Where the Sticks are?

Ornithology takes a look at different birds nests this week!

Guest Post by Sabrina Appleby ’17

Last week in Ornithology class, we spent the double period inspecting the nests of a variety of American birds. When I walked into class, I thought that these nests were all going to look and seem the exact same. I could not have been more wrong. Each nest was so intricately made and contained a multitude of different materials. Amongst the many materials, the most frequently seen ones were grass, sticks, spider webs, feathers, mud, and moss. Here are a few that stuck out to me:

1. Robin’s Nest
Created with mud and sticks, a robin’s nest is perfectly circular. Mr. Cone told us that the materials are gathered by the male robin and the female makes the nest. She uses her body to sculpt the nest in a way that provides the circular shape.

2. House Sparrow Nest
This nest is pretty gross. These lovely birds essentially gather up a bunch of grass, trash, and feathers and blend it all together in a messy heap of stuff. At least it’s an easy nest to identify?

3. Downy Woodpecker
This one’s pretty straightforward – just some bark and holes.

Submission 5-3

4. Speke’s Weaver Bird
Made of almost entirely of grass, the nest situates similarly to a bee’s nest – circular, sometimes hollow inside, and suspending from a tree. Often times, this bird hangs upside down from the nest, clinging on by its feet.

These are just a few of the 20 nests that we looked at last week. In addition to learning more about the homes of these curious creatures, I also learned that Andover has wonderful resources to research birds and their habitats. Sometimes we take for granted all that PA has to offer. I encourage my readers to check out the casing on the first floor of Gelb that holds a variety of birds. Even if you take just a moment, you will see some pretty cool bird features up close and personal.

As always, thanks for listening. Check back next week for my take on John James Audubon – our next topic of the term.

Which Came First – the Bird or the Egg?

Ornithology Students Discover Nests in Various Parts of Campus

Guest Post by Peyton McGovern ’16

Hello Ornithology blog Readers,

This week’s ornithology field adventure was by far our most exciting yet! We had our first sighting of the chipping sparrow and got to see many eggs and new nests on campus. Mr. Cone brought his extended mirror tool on the trip, which allowed us to see the nests more closely. We traveled to the bird blinds again where we spotted a downy woodpecker, grackles, and gold finches.

Over the first half of the term, my class has gotten really good at identifying the birds we learn about in class on our field trips. Instead of asking Mr. Cone for help, we are often able to reassure one another, which is really great progress.

On Saturday, I traveled to Deerfield Academy, where my track team spotted a bald eagle flying overhead in the late afternoon. It was quite remarkable to see this bird so close. I was amazed by the eagle’s wing span and beautiful flight pattern.

In the upcoming week, we have another test on bird mating strategies and bird songs and calls. In addition we will do another field day!
