I want to build a birdhouse - what glue is safe?

I want to start building outdoor bird houses, and thought about gluing natural objects to it rather than painting it. Is there a glue that is waterproof and safe for the outdoors birds? Obviously nothing will be inside the birdhouse.

Avian pox or conjunctivitis?..or neither? *feeders have been taken down

Poor little finch 😞 She was moving & eating just fine but it looks painful/uncomfortable. Avian pox or conjunctivitis? Or something else entirely?

*All feeders have been taken down & disinfected and won’t go back up for a while.

How do I help it?

So I live in South Western Australia and went to my outdoor shower where I come across a bird(wet and drenched) on the floor not flying away and just behaviour that I would consider injured or possibly it’s young I’m not sure I’ll show a video of it to explain what it’s doing but it’s like sticking its head out opening and closing its mouth without sound? Please help thankyou

Binoculars - recommendations please

I’m visiting Australia later in the year (I live in the UK) and I would like to get some binoculars. My budget is up to about £700 and I want something that isn’t too heavy.

Can anyone explain what is up with this great blue heron’s eyes?

Hello! So I have seen this particular great blue heron in my local park for maybe the past 2 years now, and I’ve noticed that he has that one solid black eye while the other is normal. What would be the cause of this? A friend said maybe it’s similar to gannets and had the avian flu and survived? Just curious and would love to know, thanks!

I found a dead bird on my university campus; is it okay to bury it?

Please tell me if this isn't the right place to post this. I've tagged this as NSFW just in case but there's nothing gory.

I found the body of a dark-eyed junco on a bit of concrete that wraps around one of the more window-laden buildings on my college campus. I saw it on my way to class this morning and when I came back it was still there.

I want to take the poor guy and lay it to rest under a tree or something, just somewhere peaceful where it can rest. Is this okay to do so long as I wear gloves and thoroughly wash my hands afterwards? I'm trying to be cautious because I know cases of avian influenza are on the rise and I'm not sure if I should report it or something. But I want to give the little guy the dignity of a quiet resting place.

Goose with limp

Hello, there is a goose I’ve seen a couple of times behind my apt that has a severe limp. Is this something I should report to a bird rehabilitator, or is it best to just leave it alone?

Do purple sandpipers have webbed feet?

Linked is a website claiming purple sandpipers are fast swimmers, using their webbed feet to escape predators, but i cant see any actual webbing on any photos of their feet.

https://www.bird.bot/guide/purple-sandpiper

Does this really count as "webbed"?

SE FL Bald Eagle Nest update (TW: death)

I don't know if this is an okay place to post this, but I felt the need to share my pain. The two eaglets that hatched about 40 days ago (I posted about them.) have died in these last couple of days, a little more than one day apart. They both had the same symptoms (imbalance, tremors) in the minutes before they collapsed. It's still just speculation at this point as to what caused this, but the local "authorities" have taken both remains in for necropsy.

It's been devastating for the community of watchers, and I can't believe how upset I am. I get such enjoyment in watching the birds' activities: the parents preparing the nest and visiting their different haunts and the kids hatching and being raised to fledging. I didn't think about it in these terms until a friend voiced it: I love them.

And now the watching and praying is being done in hopes that the two adults (M15 and F23) remain healthy.

In case there's interest, the main camera (and info about the nest) is at https://dickpritchettrealestate.com/southwest-florida-eagle-cam/?cam=1#google_vignette. Second camera is off-center of nest since the female nudged it weeks ago. Pond camera (and 360° cam?) can be watched currently only on Youtube. Current season's history of the nest can be read (and observations can be added) at https://forum.hancockwildlife.org/viewtopic.php?f=44&t=755&start=4065.

Edit: spelling

Muscovy duck murderer? What did I just witness?

I think I just saw a large muscovy duck attempting to drown another one. I'm rattled and in search of answers.

I was walking past a pond and saw a muscovy duck repeatedly push his head against the water. It seemed strange so I kept watching and realized that a smaller muscovy duck was pinned under it (held completely under water), and every time it poked its head up the larger one pushed it back under the surface. It seemed pretty obvious what was happening.

I sprinted over and the larger one was still at it so I shouted at it and it flew away. The one being held under the water popped back up and exited the pond in quick order. Another smaller muscovy duck had been watching off to the side and joined it. But then they went back into the water with the big murderous one??? I stayed for about 5 minutes and the large one kept rearing up at the smaller ones, but they all stayed in the pond together so eventually I left.

Is this a thing that's been observed before? Did I misunderstand what was happening? I saw a pigeon mating with a dead, car-flattened pigeon several years ago and I don't know what to think when it comes to birds anymore.

Just saw a pair of Phainopepla in my yard, north San Diego county.

Let me start by saying that I know nothing about birds... But I have been bringing in a bunch of native plants to my yard and finally bought the book birds of southern California trying to identify all the new critters coming to my yard.

I just saw the craziest bird... Definitely a male and female pair of Phainopepla, according to my book. Never seen these in my life.

I am curious if they are rare in this area? I'd love to know more information than what my guidebook tells me. I would go straight to Google but I'm so giddy with excitement that I had to share it with somebody else.

Why not hunt Mute Swans?

I live in the Northeast US and was just curious why people do not hunt Mute Swans as they are an invasive species that competes with native waterfowl.

I understand that they are a pretty birds and people have grown attached to them but that does not seem like a good enough reason that they shouldn’t be managed.

With the recent rise in avian flu I am also curious if they have an impact on spreading the disease.

Any thoughts or opinions?

Robins in N Fl

I live in N Florida and the cold snap seems to be over. Now all of a sudden I see tons of robins in one particular tree in my yard every morning. They are flying around very actively. It’s very cool, but I’m curious if this is part of a migration pattern or something?

Bird Flu & Feeders

My state has recently said that bird flu has made it here. What should I do regarding my 2 bird feeders that are on my apartment windows? Should I take them down entirely for now? Buff up cleaning practices (and if so, how much)? Monitor for weird behavior?

Cardinal with malformed bear?

Can anybody help me understand what could be going wrong with this cardinals beak? He just started coming to my feeder a day or so ago. I’ve had other cardinals with more regular beaks, so just trying to understand if this guy is struggling! Thanksb

Question about gliding

Hi folks! I’m working on a tabletop fantasy game and decided to make Harpies a playable race. I’m thinking about the mechanics of how their flight would work and I have a strange question that I don’t know how to phrase well enough to do a Google search. When a bird is just gliding, not flapping its wings at all, how much altitude do they lose compared to how far they move forward on average? Thanks for your time friends

What Laid This Egg?

My wife sent me this. It is in the corner of my ground floor apartment patio. Eastern Nebraska, US. Any ideas what would lay this here mid winter? We have had a redtail Hawk perching on our patio chairs the last week or so, but that does not seem to be a Hawk egg.

Is water fowl hunting as eco friendly as some claim?

I love birds. I'm an amateurish birder, but many of my colleagues hunt geese and duck. Almost all of them claim what they're doing is environmentally friendly if not necessary - an solution to over population. But looking at different species and tags available (snow geese, merganser etc) you can get license for, is this ecological management of population or all talk?

Harris's Hawks of Jacumba, CA.

I'm heading over to the town of Jacumba, CA soon to check out the local population of Harris's Hawks. This presents a unique situation to see these hawks in California rather than their usual range. I've never seen one of these raptors before since I'm based in southern california so I'm looking to get a good view of them and check them off my life list. I wanted to ask a few things in case anyone here has any expertise in this kind of stuff:

  1. How do populations of hawks like this spring up outside of their usual range?

  2. Does anyone have any specific information or research on how this specific population of birds ended up here?

  3. Howcome these hawks remain isolated to this area instead of moving around or branching out?

Thanks!

Why are male cardinals scared of this suet ball?

Every time I put up this suet ball, the male cardinal gets spooked when approaching the feeder and instead decides to ground feed. When it’s not up, they are constantly at the feeder.
