ширхӯр

ширхӯр: mammal

Дар Тоҷикистон 48 (чилу ҳашт) намуди ширхӯрҳо мавҷуд аст.
In Tajikistan 48 kinds of mammals exist.
То соли 1950 дар тамоми дунё яксаду шаш намуди ҳайвони ширхӯр нест шудааст.
Until 1950 in the whole world one hundred and six kinds of mammals became extinct.

Bonus:
ширхӯр = шир (milk) + хӯр(from хӯрдан: to eat)
Often, especially in print, the suffix он is used to pluralize living things, thus, ширхӯрон is another way to say “mammals”.

If you have a better translation for the sounds that partridges and waterfalls make, please make a note in the comments and I may change it.
In Tajik there are a lot of great words for sounds of things. Onomatopoeia is the formation of a word from a sound. In Tajik those are called калимаҳои тақлидӣ. The word тақлид means imitation or mimicry. Here are a few examples. This would be a fun thing to have a conversation about, so if you know of others please write them in the comments.
шибир-шибири борон: the drip-drop of rain
чир-чири малах: chirping of locusts
пичир-пичир: whispering
гулдур-гулдури раъду барқ: the roll of thunder
тақар-туқур: crashing and banging
ак-аки саг: the barking of a dog

Residents said that in the past half year the snow leopard has killed more than 70 goats and sheep.
Вале мардум медонанд, ки паланги барфӣ ҷонвари нодир аст ва аз ҳамин хотир кӯшиш мекунанд, ки ба он зарар нарасонанд.
But people know that the snow leopard is a rare creature and therefore they try not to harm it.

Bonus:
Adding the suffix ӣ to a noun changes it to an adjective.
барф: snow (noun)
барфӣ: snow, snowy, of snow (adjective)
These sentences were taken from an article on the Ozodi website. Here is the link if you would like to read the whole thing: Сокинони Бартанг паланги барфиро озод карданд.

In English we have words for different kinds of meat, like beef and mutton; but in Tajik they just say cow meat and sheep meat.
