Additional comments – there is a pair of Fish Crows nesting in the woods on the north side the upper playground field. At various times during my visit I observed them carrying nesting material in that direction. Individual crows were often seen flying with nesting material from the north of the school building, stopping in the trees along the south-eastern side of the school. They would sit for a while before flying several tens of yards on toward the upper playground. A few minutes later they would be seen flying back without any nesting material. Why do you think the crows would fly to a spot a good distance from where the nest is and wait before going to the nest and adding the nest material?

The front of the school and the upper playground were the most productive areas for observing and hearing birds. In the future these area should definitely be checked out for bird surveys.

I hope students have more opportunities to observe birds.  Look at other Schoolyard Bird Surveys here in my blog to see what differences there are between different schools and between the same schools from different years.

Owl Pellet Study at Ostrander Elementary School

In early April as part of my Ecologist-In-Residence program at the Ostrander Elementary School in Wallkill, NY, I worked with 2nd graders dissecting owl pellets to see what owls eat.  Here are our findings.

With Mrs. Lupoli’s class we dissected 13 pellets and found 33 mice, 2 shrews, 1 mole and 1 bird.

With Mrs. Busse’s class we dissected 13 pellets and found 34 mice, 2 shrews, 0 moles and 0 birds.

With Mrs. McQuiston’s class we dissected 12 pellets and found 33 mice, 2 shrews, 0 moles and 0 birds.

Our total findings were 38 pellets dissected producing 80 mice, 6 shrews, 1 mole and 1 bird.  I had presented to the students the hypothesis that mice are the most favored food with shrews being second favored and birds and moles tied for third.  Do the findings above support this hypothesis?

In the years that I have been taking apart owl pellets I have noticed that there are variations in the numbers and kinds of animals eaten by Barn Owls (the owls that produce the pellets used in my programs).  Could these be related to the seasons?  As a start to answering this we should see if there are any consistencies with pellets dissected the same time each year.  I have some data that we can look at by looking back at what Ostrander ornithologists have found in the past. Here is what we find:

2011 – 29 pellets produced 61 mice, 11 shrews, 3 moles, 1 bird

2010 – 36 pellets produced 72 mice, 9 shrews, 3 moles, 2 birds

2009 – 27 pellets produced 57 mice, 5 shrews, 0 moles, 0 birds
These numbers do seem consistent each year. I wonder if there would be a difference in numbers if we compared these findings with pellets from a different season than early spring, for example late summer or mid-winter. Check out my blog archives for owl pellet dissections done at other times of the year. Let me know if you find a difference.

There are certain times that might be better for looking for birds.  Looking at what each of the classes found.  Why are there different results?  Is there a better date to look for birds?  What might be the reason or reasons that more birds are found at one time of the day versus another?  Why would ornithologists record weather information when doing a bird survey?  Could there be habitat differences that make finding birds at one school better than the other?  How would you find out about this?

Note that the birds are listed in the order that you will find them in most field guides.  These lists are put together by ornithologist after studying how birds are related to each other and how scientists think that those relationships evolved, with the first birds listed being the more primitive and the last being the more recently evolved.

I have included an ornithologist’s shorthand that can be used with field notes.  This shorthand system uses a 4 letter abbreviation for each kind of bird.  It uses the following rules:  for a bird that has a common name of one word, the first 4 letters of the word are used, for example, the mallard is Mall – I capitalize the first letter, some people use all caps; for a bird that has a two word common name, for example Blue Jay, the 4 letters are made up with the first two letters of each word, in this case BlJa (again I like to capitalize the first letter of each word); for a bird name made up of three words, like Red-wing Blackbird, use the first letter of each of the first two words and the first two letters of the third word, RWBl (again for me, using caps for the first letter of each word) and finally for a bird that has a four word name, like the Great Black-backed Gull, use the first letter of each of the four words, GBBG.  There are a few cases where two birds share the same letters with this system, for example Barred Owl and Barn Owl.  In these instances you have to look up what ornithologists have decided to do for the abbreviations, which in this case would be BdOw and BanO (there is no rhyme or reason, as far as I can see, for the selection of letters in this case).

Here are some interesting notes.  The Canada Geese seen with Mrs. Bouck’s class were flying as a pair.  Keep an eye out for this.  When you see Canada Geese at this time of year they will most often be in pairs.  These are mated pairs, they mate for life, that are getting ready for the nesting season.

After I had finished exploring with the 2^nd grades I saw a hawk fly by giving a call that sounded a lot like a Flicker call.  I was not familiar with this hawk call so I did some research using Stokes’  Field Guide to Bird Songs - Eastern Region, an audio field guide, and found out that it was Cooper’s Hawk.  I am sure you can google Northern Flicker and Cooper’s Hawk and find out what they sound like.

There was one interesting non-bird observation.  With Mrs. Bailey’s class we searched for birds along the edge of the field just beyond the north eastern corner of the building.  We had been standing at this spot for several minutes trying to find birds that might have been hiding in the bushes along the edge of the field when a Cottontail Rabbit burst out from its hiding place in the bushes and hopped across the open yard to bushes in a different area at the edge of the field.  Why did the rabbit leap away from the good hiding place it had?  Why did it take so long for it to decide to change hiding places?

I have done a bird surveys in the past with both Ostrander and Plattekill students, and with students from other schools.  Check my blog archives for those results and compare them with the results reported here.  If you have any questions I would be very happy to try to answer them.  Keep up your scientific work and good luck observing birds throughout the year.
