Is the word pássaros the same in Brazilian and European Portuguese?

Yes

The word "pássaros" is identical in spelling, grammar, and fundamental meaning in both Brazilian and Continental Portuguese. The only difference is pronunciation:

• Brazilian Portuguese: The vowels are more open and clearly articulated. The rhythm is "syllable-timed," meaning each syllable is given a more distinct and equal duration, making the word sound more melodic.
• Continental Portuguese: The vowels are more closed, and unstressed vowels are often reduced or almost "swallowed" (vowel reduction). The rhythm is "stress-timed," which gives the word a more clipped, consonant-heavy sound.

Brazilian Portuguese Examples:

1. Os pássaros estão cantando muito hoje. (The birds are singing a lot today.)
2. Eu adoro observar os pássaros no parque. (I love watching the birds in the park.)
3. Tem muitos pássaros coloridos nesta floresta. (There are many colorful birds in this forest.)
4. Os pássaros fizeram um ninho na nossa árvore. (The birds made a nest in our tree.)
5. Você ouviu o som dos pássaros logo cedo? (Did you hear the sound of the birds very early?)

Continental Portuguese Examples:

1. Os pássaros cantam ao amanhecer. (The birds sing at dawn.)
2. Gosto de observar os pássaros no jardim. (I like to observe the birds in the garden.)
3. Existem muitas aves nesta região. (There are many birds in this region. — Note: A Portuguese person often uses "aves" to refer to the broader category of birds.)
4. Os pássaros voam para o sul no inverno. (The birds fly south in the winter.)
5. Vi uns pássaros muito bonitos na floresta. (I saw some very beautiful birds in the forest.)
