She enjoyed counting the birds to keep her stats up to date.

For the best eccentric lady bird watcher on film see Joyce Grenfell in Forbidden Cargo.

I had an old maid schoolteacher for an aunt when I was a kid, and though it never dawned on me then, she always hung around with two OTHER old maid schoolteachers.so maybe they were all three lesbianswho knew?

She's good at crossword puzzles, although she loathes jigsaw puzzles.

Ms. Bundy's other areas of expertise;
She makes the perfect dry martini.
She can start a perfect fireplace fire in minutes.
She can tell just by the sound when the carburetor needs adjusting.
She doesn't touch the carburetor though, she knows who to take it to.
She hardly ever misses when skeet shooting.
She can describe any character from any Agatha Christie novel and has always figured out the ending before hand.
She makes a mean deviled egg.
She mentally grades letters when she reads them.
She detests lists like this.
. Ephemeron.

I think the beret Mrs Bundy wore is a sign she is an intellectual. I'm sure she had a suitable bird-watching alternative.

Bodega Bay is a big bird-watching destination, did you know?
Birders don't tend to dress fashionably while out bothering the wildlife, that part of the bad rap is fair. Good boots, floppy cloth hat (berets won't do BTW), baggy clothes with dozens of pockets for camera equipment or your reference library. I'm a sharp dresser in town, as are many birders, but a birder needs to be able to slog through woods and marshes without being slowed down by their clothes.
Seventy-seven courses and a regicide, never a wedding like it!

Bird watchers get an unfair rap. Ms. Bundy knew about birds, but I suspect she had few other areas of expertise. I'm reminded of Miss Jane Hathaway who was a bird watcher on the Beverly Hillbillies. Although Miss Jane was a least trying to get Jethro into the woods with her on one of her expeditions.

Absolutely. And you know that when she went bird-watching, she really, really enjoyed it.
I want the doctor to take your picture so I can look at you from inside as well.

I wouldn't say THE highlight but is a highlight.
You know if you get one chance to be in am movie with a bunch of other people, and something bizarre like a million birds, do something to make your character stand out. She did!
You know you can see and hear her right now and probably haven't seen that clip in awhile.
Ephemeron.

I hope so. She was the highlight of this film, for me.
Just stellar.

No just old.

Ms. Bundy (no Ms. back then!) looked, dressed and talked exactly like a neighbor we had as kids. She was a retired school teacher, never married. She scared us (avoided her side of the street). So she was old school! Was she lesbian? Probably!
Ephemeron.

Like a pre Rosie O'Donnell but not big footish? Yup yup you right

I thought her acting in this was of the highest order
Even larks and katydids are, supposed by some, to dream

You negatory little kiddies try to take the fun out of orgasms.
But thank god you don't know how.

Probably a widow, judging from her age and her "Mrs" title.
