Learn Hardcore Turkish: Onlar her sonbahar göçmen kuşlara eşlik eder. - They accompany migratory birds every fall.

Her means “every.” In Turkish, when you pair her with a noun to express “every,” the noun remains singular and takes no extra suffix. So her sonbahar literally translates as “every autumn.”

Why does göçmen kuşlara end with -lara, and what does that indicate?

The ending -lara is the dative plural suffix (plural -lar + dative -a). The verb eşlik etmek (“to accompany”) requires its object in the dative case (“to accompany to someone”). Because kuş (“bird”) is plural here, you add -lar for plural and then -a for dative, yielding kuşlara: “to the birds.”

What role does göçmen play before kuşlara, and why doesn’t it change form?

Göçmen is an adjective meaning “migratory.” Adjectives in Turkish do not take plural or case endings when modifying a noun. All inflection goes on the noun (kuşlara), so göçmen kuşlara means “to the migratory birds.”

Why is the verb eder used instead of ederler, since the subject is plural Onlar?
