jeff, ya think its because their parents came from Placer County?
i noticed that when in boat, critters (egrets, bullfrogs etc.) arent scared of me. in middle of day, egrets keep feeding in shallows and i can row right up to bullfrogs and almost reach out and grab them. in fact when i take the wife or her niece for a little ride its fun to scare em by getting so close to bullfrogs they almost jump in boat. however, when i walk up on them from shoreline, they take off ASAP, you might try that technique w/ yer feathered friend, but remember, safety first...wear hard hat, gloves, safety glasses and steel toed boots
your one foot tall stalker is likely a green heron or black crowned night heron.
bz, i havent spotted any parasites in fish out here in 10 years, but if i do, i'll likely take issue w/ my shorebirds.
CG, there are a couple different kinds of egrets most common in CA are snowy and great. the great gets 3 ft tall and has a yellow bill, snowy gets about 2 feet tall, has a black bill, and breeding males have beautiful fluffy feathers (plumage) which almost caused its extinction in CA. the great egret is sometimes called a white heron.
you might also see a sand hill crane, but they are not stark white like egrets, and are usually found in big marsh areas in the CA central valley
sorry to hear your minnows are almost gone, i would think factors other than just the birds caused this, or maybe they are just hiding out of yer site?
BarO, when i close my kitchen door and walk outside, our GBH leave the pond, they are either really smart, really shy, or both.
