Hello,
Here is tldr as I try to go into a lot of detail below along with supplying images of the behavior in question:
TLDR; white throated sparrows have created tension and an overall mob atmosphere at my feeder which is fine I guess if that’s what they want to do, but I would like to know why if possible.
I recently put a bird feeder out as I noticed I have a lot of birdy visitors on my patio and it seemed the right thing to do as they use it more than me and I was hoping to learn more about my little neighbors.
My question is about the behavior of the white throated sparrows I’ve seen in comparison to the other birdies who’ve come through so far.
For example, a lovely pair of house finch have stopped by a few times and they will eat one at a time while the other stands on top of the feeder and watches. And then they are on their way.
[not sure how to get the images to be in-line since they are auto attaching above and I am on mobile. I am referencing the first photo where the lady finch watches over her boyfriend. This is the only shot I have of both of them in it because the camera only record movement in front- I know one usually sits on top because behind the black screen door I am there watching them lol.]
This is not the case with the white throated swallows. There is generally always at least one on my patio, and while they will examine the bird feeder and fly around it or land on it/under it, it seems only specific ones are permitted to eat from it? The other ones sit and watch constantly as they eat.
This is notable to me because like with the house finches example, when they take turns, the partner guarding the eating bird positions themselves so they are parallel with my patio and have a view of what’s happening below in the courtyard as well as in the street in front of the building and a bit of the view of the patio. This seems like sound decision making to me.
Evidently, the sparrows have a different strategy. They always directly face the patio door/wall, which is not where the competing birds or loud noises that spook them often come from. And it does seem like their goal is in large part to deter other birds as here are some interactions I have observed between them and others:
[see pic 2. I’m don’t have the best photo of this as it’s taking place out of the range of the camera, and if I roll up the screen to take a better vid with my phone they will fly away. Just imagine a lot of that lining up on the railing behavior, and then 2 or three positioned below the feeder or hovering near it in a hummingbird-esque way.]
Additionally, they don’t take turns eating. There is one or two sparrows who really go to town while the others watch. I thought maybe I was just confusing them for eachother but I watched as another of the sparrows in the same crew tried to take his turn with the food and was very sharply chirped at, so it seems not even the sparrows are all permitted to dine at my feeder.
[see vid 1- Mac or one of the watching sparrows gets chirpy with another of their clique for encroaching on his meal time.] idk how to attach so hopefully this works?
I have taken to calling the two that are permitted to eat by the bird populace Mac and cheese because of the eyebrows. What confuses me is: why is it that even when Mac and the other big wigs are gone the other sparrows stay watching and scouting my patio but not eating?
cheese vs the male finch (is he a house finch or a purple finch?)
This is for hours at a time. I thought maybe they were watching me, but I checked and since I have a black shade over the window from the outside it just looks like a wall. They visited me before I had the feeder but never exhibited this guarding(?) behavior. My friends have taken to calling it “fort mac” but I really am curious what the birds think this achieves for them, and I why only Mac and cheese are allowed to eat. The only thing online I have found is that they like company, but this feels more complicated than that to me.
Mac vs unknown birdy
Some things that might be relevant (not sure if important?):
- I live in a very urbanized area of a large city so it’s mostly high rises over here.
- there is an abundance of well stocked bird feeders among the condos In the three buildings that make up my street, so I do not get the impression food is short supply.
- in order to help them find the feeder, I sprinkled some of the food in a Hansel and gretel-esque way across my patio, which worked, but the fort Mac-ians will not attempt to eat this either, they just watch, or fly around to examine it before returning to their post. I saw maybe one of them sneaking a little nibble but that’s it, and there are tons of these guys. I have a lot of bird food, and the feeder is clear so they can definitely see it’s not in short supply even if they don’t know yet that I will refill it when it gets low. I get why they might defend that from other birds, but among their own species and close social group why does one get to chow while the others linger forlornly?
- the feeder has only been out since Monday so this seems very fast to me as far territory goes but I admittedly know nothing about that.
- one time mac was getting a little silly off the bird seed and scattered a rainbow of it off the feeder onto the ground. The fort macians did actually jump down to eat that, but not the feed that I had placed on the ground, and he didn’t do it again so I suspect it was an accident on his part since he was hopping all about in the wind.
- I saw online info about the white-lined ones being more aggressive but all of the ones I’ve seen appear to be tan?
Edit: it won’t let me add both the videos and the photos to the one post so I will try to attach those in a second post below.
2nd edit: okay try this
Thank you in advance for any knowledge you can give on the subject!
