I have these & they are FANTASTIC for a crate! They can't knock them over or poop in them if you put them high enough & are perfect to clean & refill from the outside so they can't escape when refilling. Works great in my broody breaker crate. (not that anyone was asking, I just like them so much I thought I'd share, lol)I have clip on cups like you use for rabbits, and a tower one that is smaller like you have for parakeets.
The parakeet one is great as it's a small quantity for clean water/med change daily.
I've lived on a couple lakes - they are a nightmare!As a kid, Canadian geese would regularly chase us, honking and hissing...even if we didn't get close to their babies. They also poop EVERYWHERE. Every summer we have several lakes that inevitably get shut down to the public due to e.coli problems related to goose feces.
Looks nice out there, but it's too cold & the snow is to deep for me to actually find out.

I ordered 2 more greenstalks yesterday for the sale - I should be good to grow all that I want this summer. I have 2 collapsed cedar raised beds to get rid of (they only lasted 4 or 5 years) & some of the greenstalks will go in their spot. This is my list of things going in the greenstalks this year, each one gets their own:
Peppers
Lettuce/spinach/arugala
Onions
Strawberries
Bush beans/edamame
Turnips/Celery/Mini eggplant?
Speaking of drip irrigation - it's getting put off another year. My disability & all the changes to the garden because of it has sent that want to the pending pile, lol. We'll see how the new set up goes this summer & maybe next year I can do an automatic system.
