Lesser goldfinches and sick ducks

Early Christmas morning brought lesser goldfinches.  This male wasn't afraid of me at all:

These females weren't afraid of me either, until the sunshade on my camera fell off and they flew away, but the male stayed and called for them.

This duck has a very cute bill.  I've never seen a bill marked like that.  I think she's a young duck.  I was sitting down and she walked right behind me and chattered away.

For the last few days, I've been getting help for this crested pekin female.  I was told she might have ascites, or water on the belly.  The first day I saw her in trouble, she was very sleepy and looked sick.

When I saw her yesterday, she looked a bit better, but was still struggling.  I did see her run out of the water when someone brought some food.  However, someone said she suddenly started limping and then collapsed on her belly and scooted herself back into the water.  When I saw her, she was acting like something was wrong with her legs, but got better as she continued swimming.  She also put her wings and tail back into normal position for a moment.

If it's ascites, she will NOT get better and will die within days.  If it is not, then I don't know.

Update:  It took me a while to get some help for her, but she was rescued on 12/29!  She is said to be extremely thin, but other than something being wrong with her leg, she seems to be OK.

Across the lake from that duck, I thought that this female on the left had a bad bumble on her foot.  If she does, she may also die from that and, perhaps, infect the other ducks.  That's her mate on the right:

Someone said that might not be a bumble, but a callous.  It's making her limp, but she seems to be a very happy girl and in love with her mate.

I'm sad to report that this small duck who has been at the lake for several years is either sick or injured.  He was fine a week or two ago.  He is acting normally, but is all hunched over.  He might have been attacked by a larger duck or even a predator.  I don't know how old he is, but he might recover.  He's probably a call duck mix and is just about the smallest mallard-derived duck at the lake.
