Australian Swamp Rat (Rattus lutreolus)!
Most Australians don't know that we actually have our own native species of true rats, such is that little cutie that I found at Mt Tomah today.

Birds are dinosaurs who shrugged off a couple apocalypses. Some eat bone marrow. Some drink nectar. They outswim fish in the sea. They smile politely at gravityโ€™s demands. โ€ฌ

The Curved-billed Thrasher has a shorter and straighter bill than LeConteโ€™s, Crissal, and California Thrashers. When naturalist William John Swainson first described the Curve-billed Thrasher he had not yet seen these other three species.
