However who can blame them for that? Of all the sea animals, the octopus is probably the most intelligent, blue whales are the most significant, and goldfish are neither. However to be reasonable to the bad little person, he's pretty adorable for his size, and he's not as dumb and absent-minded as you may have heard.
They can even tell time. In lab tests they might be conditioned to press a lever for food at roughly the very same time each day. That 3-month memory is a lot longer than 7 seconds. They require a fairly long-term memory in order to find and remember food sources and avoid the hideouts of their predators.
Duck quacks, honks, yelps and squeaks do echo. Maybe this myth developed from the landscape of duck ponds. When a duck quacks from a low-lying duck pond, in a flat landscape, there's nothing for the acoustic waves to echo versus. And even if there were some hills and mountains nearby, the quacks might be too faint to produce an audible echo.

Overall, mom birds are a lot more faithful to their babies than this myth recommends. Life-spans in the animal kingdom, even within a species, can vary commonly.

The oldest dogs cracked 29 years, and the oldest cat broke 38 years. While our unwanted buzzing guests, the common houseflies, don't average nearly as long a life-span as our's, they can live up to a month. This myth probably mistakes the housefly for the mayfly, which, depending on the species, may have a lifespan between 5 minutes and 24 hours.
Being big birds with little heads, it might appear like they are concealing their heads whenever they flex down for food or nose through a small hollow for roots and seeds. So what do ostriches do when frightened? They can run pretty fast, up to 31 mph. For comparison, the top speed clocked for any human is 28 mph.

It's not the most interesting defense reaction, but apparently it works. The theory is that when a wedded couple walks the onslaught of tossed rice, the ground is left covered in dry rice.
