It looks like it would be a good idea to purchase a Senior Pass prior to

Re: [cayugabirds-l] Why larger predatory birds flee smaller birds

[Mike Pitzrick]

A couple of years ago by the Lab of O I saw a Canada Goose repeated land on
the shoulders of a white-tailed deer and peck the back of the neck and
head, driving it away from a nearby nest.  I seem to recall that some of
the Lab staff chose an alternate entrance to the building for a couple of
weeks to avoid this aggressive gander.

I have not really, not yet, talked with otter
about his life.

He has so many teeth, he has trouble
with vowels.

Wherefore our understanding
is all body expression —

he swims like the sleekest fish,
he dives and exhales and lifts a trail of bubbles.
Little by little he trusts my eyes
and my curious body sitting on the shore.

Sometimes he comes close.
I admire his whiskers
and his dark fur which I would rather die than wear.

He has no words, still what he tells about his life
is clear.
He does not own a computer.
He imagines the river will last forever.

He does not envy the dry house I live in.
He does not wonder who or what it is that I worship.
He wonders, morning after morning, that the river
is so cold and fresh and alive, and still
I don’t jump in.

I see from the minutes of the 10/16/2013 Lansing Town Board Meeting

Re: [cayugabirds-l] Not birds-but FIREFLIES tonight

[Mike Pitzrick]

Hi Dave,

People do perceive colors differently due to both biological capacity and
training.  This is an area of active research.

Regarding biological capacity, most people have three types of color
receptors in their eyes, each of which is most sensitive to a single color:
red, green, or blue.  Some people, mostly male, are completely or partially
color blind, meaning that one or more types of color receptor are partially
or completely disabled color receptors, resulting in diminished capacity to
discriminate differences in color.

Recently it was discovered that some females have four types of color
receptors in their eyes, giving them the potential to distinguish more
colors than is usual in humans.  This article in Discover magazine, Humans
with Super Human Vision
http://discovermagazine.com/2012/jul-aug/06-humans-with-super-human-vision,
explains.

If you are interested in testing your ability to discriminate colors, try
out this Color Test http://www.xrite.com/online-color-test-challenge.  If
you'd like to see if you are color blind, check out Free Colorblindness Test
http://www.colour-blindness.com/colour-blindness-tests/.  Note that these
online tests are not 100% reliable, due to variation in computer monitors.

By the way, this discussion is pretty far afield from the usual content of
CAYUGABIRDS-L, and I'm surprised no one has complained yet.  People who
would enjoy participating in a similar email list with broader scope may be
interested in NATURAL-HISTORY-L.  Instructions for joining a Cornell email

Re: [cayugabirds-l] Bluebird bot? flies

[Mike Pitzrick]

Hi Richard,

There's a chance that what you are seeing are bird blow flies.

Bird blow flies are common in the nests of many birds, including bluebirds,
 swallows, chickadees, wrens, warblers, flycatchers and raptors.  Research
 shows that heavy infestations can make nestlings anemic (cause reduced red
 blood cell counts) and severe infestations may be lethal (Whitworth 
 Bennett, 1992).  Infestation rates vary from almost 100% in magpies to 50%
 in many bluebirds, to zero in over 100 oriole nests (Whitworth  Bennett,
 1992).  In most areas, around 5-10% of infested nests are likely to have
 sufficient larval populations to make nestlings sick.  Little is known
 about this parasite since it is rarely encountered in nature, except in
 bird nests.

 http://www.birdblowfly.com/generalinfo.html


Terry Whitworth, the investigator who put up the website linked above,
invites readers to send data from their observations of bird nests.

If you should disagree with Terry's opinion that it is best to allow blow
flies free access to bird nests because they are perfectly natural,
http://www.sialis.org/forumlinks.htm offers some advice about controlling
blow flies in bluebird boxes.

 Can anyone tell what the species might be? Have collected them and are

 What I might do to avoid these should they use the box again?

 What harm do they cause?

Re: [cayugabirds-l] Mockingbirds on our house

[Mike Pitzrick]

Hi Richard,

The range map for Northern Mockingbird in *Birds of North America*
indicates that they breed as far north as southern Ontario, and are
permanent residents as far north as Watertown, NY.  Regarding migratory
habits, BNA says it is

Not well understood. Reported to be partly migratory in northern portion of
 range, but at least some individuals remain in winter at northern limits of
 breeding range. Perceptions of status could be affected by reduced
 visibility of mockingbirds during winter.


About the number of songs types one bird can make,

The vocal repertoires of individual males have been estimated to be as low
 as 45 and as high as 203 song types ... Song types appear to be added
 continuously to the vocal repertoire, suggesting that an individual bird
 may not have an upper limit to its repertoire.


The BNA account does not appear to address the issue of the fidelity of
mimicry, so I will venture into the realm of my own impressions of how
mockingbird mimicry can be distinguished from the songs of birds they
imitate.  I would welcome commentary from others who have similar or
different impressions.

BNA mention that

Mockingbirds typically repeat one song type several times before switching
 to another. Songs are presented in “bouts,” with each bout consisting of
 repetitions of only one song type. Song types of short duration are
 repeated more often within a bout than are longer song types


This suggests one of the cues that might clue me into the fact that I'm
hearing an imitation of a cardinal song rather than a real cardinal song.
The mockingbird is likely to make several identical repetitions of the same
cardinal song in a pretty short time frame.

Beyond that, it appears to me that while many aspects of the cardinal song
are faithfully reproduced to my ear, there are definitely alterations.  To
me, a real cardinal song has more dynamic range, more change in pitch, more
variety between repetitions of the same song, more variability in song
length, etc.

To anthropomorphize, when I hear a real cardinal, I sometimes form a mental
image of an opera singer.  I hear years of voice lessons.  Each note is
milked for every possible ounce of melodrama and emotion.  I can almost see
the exaggerated facial expressions.

The mockingbird reminds me more of an advanced beginner pianist.  The
repertoire is getting to be quite large and increasing every week, but each
of the pieces is of similar length because it gets boiled down to a single
page in the piano lesson book.  The performance is lacking in dynamic
range, change of tempo, and creativity.  Each repetition is rendered
mechanically and identically.  My impression is that of a rote performance.

Does this ring true for other observers?

Richard, I'm guessing you would really enjoy reading The Singing Life of
Birds
http://www.amazon.com/The-Singing-Life-Birds-Listening/dp/0618840761/ref=sr_1_1?ie=UTF8qid=1402234001sr=8-1keywords=kroodsma
by Donald Kroodsma.  The book discusses Northern Mockingbird among other
species, comes with a CD, and is full of sonograms.

 1, How large a collection of different sounds can one bird make?
 2. I recognize some of the sounds. Would a cardinal be confused in hearing
 his call?
 3. Are the sonograms of a mockingbird and a cardinal about the same, or
 can you tell them apart.
 4. Mockingbirds migrate. Can you tell where they spent the winter by the
 songs they sing?
 5. Do mockingbirds make calls of predators like owls or hawks?

Re: [cayugabirds-l] A hint of things to come...

[Mike Pitzrick]

I just located this 2012 review paper on the topic: Photoperiodic Control
of Seasonality in Birds http://jbr.sagepub.com/content/16/4/365.abstract.
In case you can't see that link from where you are, here's a brief excerpt
from the abstract.

This review examines how birds use the annual cycle in photoperiod to
 ensure that seasonal events--breeding, molt, and song production--happen at
 the appropriate time of year ... In predictable breeders (most nontropical
 species), photoperiod is the predominant proximate factor. Increasing
 photoperiods of spring stimulate secretion of gonadotropin-releasing
 hormone (GnRH) and consequent gonadal maturation.

 Yet another reason to love birds:  after a certain point in late winter,
 they say, To hell with the temperature, I'm getting on with it!
