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
,
explains.

If you are interested in testing your ability to discriminate colors, try
out this Color Test .  If
you'd like to see if you are color blind, check out Free Colorblindness Test
.  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
list can be found in Join an E-list
.

That's a great website for a neat project, Mike! On the discussion board, a 
participant (whose name & email I have omitted here) asked Linda's question, 
and the project leader replied:

In my June 1, 2014 report I reported an individual flying with three flashes 
and reported it as orange because red was not an option. It looked RED to me. 
Is that possible?
.:Don Salvatore - 6/16/2014 1:20 pm Firefly colors are listed as yellow, yellow 
green, green, orange, amber and blue. I have never heard of a red firefly. But 
that doesn't mean that there isn't one. Or that because of the way people may 
see colors differently or environmental conditions, you won't see a red firefly.

Think it is a good year for fireflies!.  Jerseybirds had a post of a great 
display last week down in NJ. I also had one of the best displays in years in 
my yard in McGraw.

Thanks Mike and Dave. Mike, that chart is very illuminating. I had no idea 
there were that many species. Amber seems a good way to describe what I saw as 
red.  It seems a monumental brain task to sort out all the flashing going on 
but just having these different parameters in mind would help you to see 
better.

It may be that what you are seeing are multiple species of firefly.

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

[Dave Nutter]

Some stars look slightly orange or blue, but the fireflies all look green to 
me. I think the red flashes are airplanes. Seriously, I know there are 
different species of fireflies and they use different codes of flashes, but I 
don't know about different colors. I'm guessing they all use the same 
chemistry, so the color would be easiest to stay the same, and that's why they 
use timing. There wouldn't be a noticeable doppler shift for light. Maybe the 
ones seen farther from your center of vision could appear different colors if 
there's a different concentration of receptors for different colors. I know not 
all colors can be seen equally well in peripheral vision. Red is worst.

It is a nice night for fireflies, one of several lately in our yard.

It is wild out there...flashing of several kinds, low and high in trees.  Give 
that it is hard to see birds right now, it is well worth a look outside for 
this pre-4th display.

Vic Lamoureux put a similar alert out for Broome, on the Bluewing list.  
Apparently this is THE night so far if you are a firefly.
