    Had crows at my parents place pecking the windows. So them attacking glass surfaces definitely tracks.

      At a guess, because crows are smart, resourceful little chaos goblins, with basically no fear, especially in groups. Maybe they like the noise the breaking glass makes, or maybe they’re just curious to see what will happen. It wouldn’t surprise me to learn that they’ve made a game of it, to see which of them can hit nearest the centre, or from highest up. I’m actually surprised that a single falcon manages to scare them off, after seeing what they do to buzzards round here. Even if the buzzard is minding it’s own business, multiple crows will attack it in flight, dive it bombing and harrying it until it has left the area.

        Have you seen one IRL? They’re really not that but at all. Could fit in a backpack —if you have a wish to lose your soul to oblivion, but yeah. Pretty awesome, actually. 🥰

      Even further, why scapegoat the crows at all?

      The local avian population no doubt bombs enough bad paint to cause issues when it anneals to the panels in the focused sunlight. Secondly, that one falcon is quite likely taking whatever it can find on the wing each sortie. Even ground critters. So…

      Again. Why? 🤌🏼

      Yeah, I’m wondering about the truthfulness of this story also. Here in Southern California we have solar arrays and crows. They seem to coexist quite peacefully,

        “there was a high possibility of actual damage occurring, such as the cover glass being broken by falling rocks or the panel surface being soiled with droppings” from the Japanese article via google translate.

        Our crows here are larger than the US (“grackles” in Texas may be close, but I think they’re still smaller), but I still wonder if they could drop rocks heavy enough (or repeatedly enough) to do anything.

        I would also be amazed if a crow could lift a big enough rock to damage a panel. I have a pile of panels in use; they’re pretty damn tough to break that glass. Only time I’ve seen one broken was the wind tore it off it’s mount and smashed it into the top of a fence post. I measure the production afterwards and it was still 90% despite the glass being crazed across the entire surface.

    Deciding which side to support between the anti corporate anti technology crows or the bad ass green energy supportimg hawks:

      Yada yada yada… I just installed our second set of cobras under the couch. They eat the mice. The mice are for feeding the security bears, but they tend to run into the house. The mice, not the bears. The bears protect the house from the road lions who prevent cars from parking in front of the house. That’s where we have our electric car chargers fed from the solar panels. Yeah, we got the eagle to chase the falcon who chases the crows. The crows are there to prevent pidgeons so I can enjoy my fries in pace. My dog doesn’t bark at all. Cone to think of it, I haven’t seen that rascal in a few weeks. I wonder what he’s doing.

      Aviation term for an air attack. Out, hit, back.

      I think it’s also general military. A squad can sortie out to accomplish an objective.

        From the French sortir, “to go out”.

        So yeah, the “out” and “back” parts are important: if a unit is attaching while maneuvering in the field, it’s not a “sortie”. That’s also why it’s common in aviation, since airplanes inherently require a home runway that every attack begins and (ideally) ends at.

    So, that’s 2.5 sorties an hour, 24 hours a day. I don’t know how much falcon need to sleep, but that feels unsustainable.

      Now I’m wondering. How large of an area one bird could cover. How many falcons does one professional falconer have? Do they take constant upkeep training like a dog or do they retain better? Does a falcon eat much? Can they eat people food? Like two mice a day with some fish would probably be ok. Maybe let it eat some of the crows to keep costs down?

      So like 2-6 falcons, they can sleep in the van, let them eat the crows they nail. The birds are only flying from dawn to dusk, so 7 days a week for maybe 10 hours on average?

      Screw it, I’m buying a falcon.

      Based on the abstract of a research paper I found (the only source I found not interested in exaggerating things for clicks or commenting on mundane problems like nests and poop), crows know that dropping rocks is fun. The researchers (again, according to the abstract–the meat is behind a paywall, as usual) speak as if crows are always dropping rocks; the implication being that the presence of the solar panels is happenstance. Their research merely correlates cracks in the panels, and pebbles on the panels, with crows flying overhead. In the paragraph they don’t even directly blame the cracked panels on the rocks, let alone the crows. They simply state the chain of events as a possibility.

      On the other hand, I’ve heard lots of fun facts about birds over the years and the underlying theme is that birds are bastardly and some, like crows, are intelligent. What human kid doesn’t enjoy throwing rocks or shooting bullets at glass? I don’t find it hard to believe that crows might similar mayhem enjoyable.

    I’m not convinced a crow can crack a solar panel, they are very tough. People walk on them, and they survive hail.
