Is this how loud birds are?

I’m trying to make an approximate scale of bird loudness measured in decibels.

I need approximate guesses.

Does this sound okay to everyone?

Birds of India

House Crow 85 db Common Myna 75 db Rose Ringed Parakeet 70 db White Cheeked Barbet 60 db Red whiskered Bulbul 40 db Purple Rumped sunbird 40 db Common Tailorbird 40 db Oriental White Eye 30 db

What Bild?

Sag that bird today at work on an airport. It was just about 8-10in tall as well as it seemed that it was a male and a female. Equal size

Question about warbler's relationship with different warblers

I'm in San Diego county and yesterday an Orange Crowned Warbler showed up on our plumeria and was instantly joined by a Townsend's Warbler. Today, the same thing happened. Are they just hanging out, or is there a different type of relationship going on here (I don't mean as mates)?

Do we know how the Paratympanic system helps birds to fly?

It seems we believe that this system functions as a sort of barometer and altimeter which helps birds fly. I don't see much research which goes beyond that.

What I'm wondering is a bit abstract and possibly beyond the realm of what we can even study. But do we understand how birds sense this data? Is this presented to them as an additional "sense"? Like do they have a sense of the air, just like we have a sense of touch? Or maybe more like our sense of balance?

It seems that understanding the nuances of air pressure, temperature, altitude, etc would be incredibly important to birds as they evolve. So I'm generally wondering, do we think that birds perception of their aerial environments could be compared to how when a dog smells, it senses a whole entire world that is hidden to us?

I know this is an abstract train of thought that probably doesn't really have an answer. But would love to hear what people think.

Why even have an ornithology sub?

"This is a place to discuss wild birds in a scientific context — their biology, ecology, evolution, behavior, and more. "

No. It isn't. This is a sub for any and all things that might be tangentially related to a bird. "I found a feather" "What is this bird?" "Here's a picture of a bird" "These birds are flying outside my house, what should I do??"

Nothing is ever taken down, and it seems rare that anything of any substance is ever posted. Just dissolve the sub already.

edit:

Folks, your knee-jerk reactions, out of context ad hominem attacks, and attempts to shoehorn everything under the sun into "ornithology" all support my initial point. If every bird related sub bends over backward to be absurdly inclusive to every post, their value is diluted and eventually lost. Why even have a dozen different bird subs if they all have the exact same content? These inappropriate posts have much more appropriate subs in which to exist - and half of them are already crossposted to them for maximum exposure.

Quantity does not equal quality, words have meaning, and not everything involving a bird is "ornithology". Take care.

Decibel level of different birds

I’m making an Infograph about the decibel level of different birds.

Does anyone here know where I can find that data?

Birds from bangalore india. Crows, Bulbul, Myna, purple dumped sunbird, oriental white eye.

Approximations will do just fine.

Bird flew into my house

I came home around 10 PM and went to my room directly. In a couple secs my dog started chasing a bird to my room. My windows were closed so I assume it went in during morning and stay hidden till now. It went into my bathroom, I closed the door and opened the window but it doesn’t go out. I tried to catch it but I’m afraid it is going to kill itself while trying to get away from me. I’m also afraid that it won’t survive outside at this hour or cannot find his house. I don’t know what to do, should I keep the window open till morning and wait for him to go out or try to catch it ? I didn’t know where else to post so anyone have any suggestions?

Why do birds rub their beaks on stuff?

I saw a carolina chickadee do this after it had eaten from my feeder, so I thought it must have been wiping its beak to get off food residue. But then I saw a northern flicker do the same thing later on that day, and it had not eaten from my feeder. Beaks don't have nerve endings, correct? So it's not like scratching an itch. Why do they rub their beaks on a branch or something all the time? Is it a sign of something in the environment that's getting stuck on them or just a normal habit they all have? I'm in central Mississippi, and our air quality is usually pretty good, so I don't know what the problem is, if there even is one.

Why is There a Huge Difference Between the Number of Bird Species Estimated by Ornithologists and the Number of Bird Species Reported by Birders on e-Bird Over More Than 20 Years?

Researchers estimated there were 18,043 species of birds worldwide in 2016.

However, e-Bird, which started in 2002, reports a total of 10826 bird species observed up to today in 2024.

Will a widowed owl stay in my yard?

I had a bonded pair of barred owls in my yard and one was found dead this morning. I didn’t know what to do. So I called animal control and they came and inspected it and it had an injury under its wing. So they didn’t suspect poisoning or avian flu so I declined to keep it on ice over the weekend to take it somewhere for testing…not sure if I made the right call or not…it was a spur of the moment decision and I’m second guessing myself. They said they would cremate it for me which I thought would be nice. But anyway I’m so sad. I was so attached to them and now I’m not sure how I can support the other owl so it will stay or find another mate. I know they aren’t pets but I just really loved them so much. They brought a lot of joy. I’d really like to support its grieving mate. Can anyone share any advice or information on owl habits?

I’m not sure if this is the right sub or not. I will remove if it isn’t.

Update: it’s sunset and its mate is calling non stop. 😭 I don’t know whether to cry because it doesn’t know where it went or be happy it’s already looking for another mate…probably because I can’t understand owl. 😔

Update: it quit calling around 11 pm so else flew off to another area out of earshot.

Are there any studies on owl stomach-acid intensity?

This is highly speculative and has no basis in research*

Owls have a habit of spitting up pellets, we all know. I am wondering if maybe this habit has evolved with a generally weaker stomach acid. I think maybe liquifying only the fat and meat would require less caustic acid, which means also that the stool reeks less and is less intense and acrid, which is better for stealth, which owls rely on.

In contrast, vultures have super caustic stomachs and the byproduct reeks so bad they use it as a defense mechanism. Coincidence...?

Help me identify these birds

Hi. Non-Bird-Nerd here.

Could anyone help me identify the birds that can be heard in the end credits of this movie?(53:22 - 54:10)

Boards of Canada also used them in their track "The Smallest Weird Number"

Is this bird real or fake ?

Hellou I have a question. I know this bird is probably fake, but strangely the more me and my boyfriend look at it the more we cannot decide if it is real or no. We might just be going crazy at this point 😂. But if anyone is able to identify the bird or the sound of it, we would be interested what it is (or supposed to be).

It is from TopGear S12E08 - Vietnam special. Time 17:01. We noticed it because it looked ultra goofy and we could not stop laughing at it 😂.

Nearby Eagles Nest

I'm so excited and nervous! In the park by our house a pair of eagles are building a nest for the first time in this location. They're still in the nest building phase. I notified the location to the state's department of natural resources already. My concern is they're building it in the middle of a public city park surrounded by softball diamonds and directly above a playground. (A trip to the park and now I know eagles eat sea gulls lol) I'm worried they'll abandon their nest when the weather warms up and more people are in the park. But I'm enjoying seeing them while I can.

Edit: fixed a typo

Why is this crow just sitting here?

Some time ago, in 2022 I think, I found this young crow while I was on my way to grandma's house and I would like to know more about it.

Wild bird plucking feathers, why?

There is a common bird on my front yard tree plucking away at its feathers quite a bit. I walked out to get to my car and it was like it was actually raining feathers, all over me and my cars. I’m not sure what kind of bird it is, all I know is it’s an adult, gray or brown and located in south Texas. A lot of the feathers have quite a bit of red, and my yard is now full of them. I ran to my car and just got a picture of a feather stuck on my car window. This is the first time I’ve seen something like this, what’s going on with the guy?

Can Ardea intermedia (Medium/Intermediate Egrets) mate with Ardea alba (Great Egrets)?

I'm new to bird stuff and taking a university course on biodiversity and we were going through bird identification. Looking at how similar these birds are, can they produce offspring (viable or otherwise) or are there any cases of such offspring in the wild?

Question about winter mixed flock waterfowl

So I just listened to an episode of the podcast “The Science of Birds” of which the topic was interspecies competition. It got me thinking about the large winter mixed flocks of ducks that I see here in the Rockies. Redhead, Goldeneye, Scaup, Bufflehead, Ring-Necked Duck and others tend to form large flocks of interspecies communities in fairly crowded ponds. Are they not competing for the same food and resources? Are there significant benefits to winter mix flocking?

Why aren't there cardinals in the west?

Might be a dumb question, but why? They have wings, so whats stopping them from expanding to the whole U.S/North America like robins?

Surely they have the numbers and there's just as much food there as in the East.

What is it that keeps birds region locked? "Who knows, just because"?

How could I speak with an expert on woodpecker behavior?

I'm trying to factcheck some information about woodpeckers, and wanted to see who might be a good expert to reach out to. Does anyone know of a scholar or ornithologist who studies woodpeckers?

The specific question I want to answer regards a woodpecker in India called the flame backed woodpecker (Dinopium benghalense). KK Neelakantan, the great Indian ornithologist, published books and articles about the bird in the 60's, and one curiosity is that he had never observe males and females mounting, but had observed male-male mounting. I am fairly certain that up to the late 1990's there had still never been an observation of opposite sex mating. So my question is - has there been any observation of these woodpeckers mating since the 1990s, or our only records of them mating at all still from the observations in the 1960's?
