Oh, our
mailbox is just brimming with such interesting questions from
BirdCouple devotees!
We recently received this email from Doris in Port Clinton, PA:
Dear BirdCouple,
I love your blog! Read it everyday!
I have a somewhat strange question that I hoped you could help me resolve. I recently went birding with my local birding club and it seems that the vast majority of birding participants wear zip-off pants.
Please be assured that I am not asking you some sort of kinky question. I am referring to the zip-off pants that exist as long pants but have a zipper capability that allow them to become shorts.
Anyway, I wondered if this was standard birding equipment. Or is it akin to the boxer/brief issue?
I have my Alpen Binoculars , my field guide... but do I also need zip-off pants?
Thanks and keep up the good work!
Doris- first, we want to congratulate you on birding with your local birding club. Local birding clubs are a great way to learn tons about birds and birding.
In general, birders are really nice people who will be delighted to show you a new bird and teach you about birding.
Regarding the zip-off pants issue....
I, too, have contemplated purchasing zip-off pants, as I don't own a pair right now.
I went deep within the BirdCouple files to answer your question and found that ...
Well... it depends...
Not zip-offs.
Now, this was taken in February in Maryland and I was there.
It was cold. Zip-off pants are thin.
In the month of October we met Frank Caruso, Professor of Plant Pathology at U Mass in Cape May.
I was there.
It was unusually warm for October. Frank is sporting jeans. Cute Husband, zip-offs. 
Peter Kaestner, #5 in the world for most birds seen.
Unusual mild August weather.
Zip-off Pants Man.

Dan Haas, of Nervous Birds.
I don't recall ever seeing Dan is zip-off pants. Although, Dan is also a
musician. I have never seen Billy Idol or Britney Spears in zip-off pants.
Well, not these kind of zip-off pants.
Pete Dunne, October (with the scope over his shoulder).
No zip-offs, but note other birders sporting them.
Paul Baicich, author of A Guide to the Nests, Eggs, and Nestlings of North American Birds.
Paul wears jeans.
I'll test this tomorrow when I bird with him in 80 degree weather.
New birders at Keswick Hall. I don't see any zip-offs.
North Dakota. Jeans 3. Zip-offs 2.
So, Doris, the zip-off pant issue...
My theory is that the wearing zip-off pants is a deeply personal issue.
It may be weather dependent. It may be a birder's creative license.
But, our research shows that jeans are also acceptable birding attire.
Doris, I think the best advice we can give you is to keep birding and keep wearing some sort of pants while birding.
