As a species? I haven't seen any research showing that other animals are any better at memory. The more interesting observation would be that we tend to be a lot more confident in the accuracy of our memories than we should be.
As a species, as in our brainmeats in general ain't good at it and none of us are particularly free of the issue, even before various sorts of cognitive degeneration sinks its claws in. Haven't seen anything mentioning comparative cross species capability, but that doesn't somehow mean we're good at.
We
are a lot more confident in our memories than we have actual grounds to be, though, yeah. The implication of that being we're pretty bad at remembering stuff accurately. Drum on that front seems to be getting noticed and beat in particularly in relation to eye-witness testimony (and confessions) in legal/criminal cases, where it's getting ever more increasingly clear both are unreliable as all hell.

“Monarch of the Oceans, The Colossal Leviathan
Champion of the Swamp, The Divine King Serpent
Terror of the Seas, The Abominable Cthulhu
Majesty of the Rivers, The Seven-Headed Hydra
Beauty of the Arctic, The Enigmatic Narwhal
Devourer of Tides, The Obsidian Xuanwu
Emperor of the Lagoon, The Heavenly Sturgeon
Eminence of the Lake, The Sovereign Koi
Fish, legendary aquatic creatures of myth, and then Cthulhu.
One of these is not like the others.
