Unless you're cutting an instructional film for ornithologists don't worry about the species. This is your scene. What kind of birds do you want to hear? What sounds would enhance the feeling the movie cries out for? This is where the sound editor earns his money. Create a sound environment that dramatically does it for you and the audience will be ...
Russia is pretty huge, what part of Russia are you after? I'm in finland that is also just next door but a bit further north, so if there is something specific I could help or might even have it already.
Alternatively check out this guy http://www.kaamossound.com/ he lives further north than me and has an extensive collection of local recordings.
Hi. What kind of things are you looking for? While I don't live in Russia I am in Estonia, next door, and Estonia has lot's of wide open spaces with no traffic, airplane or human sounds. If there is something specific you want maybe I can get it for you!
I did a year of acoustical consulting (architectural / noise control) before going back the more creative sound design route. The first book my old boss had me read was M. David Egan's Architectural Acoustics. Very easy to read, with good practical principles and illustrations, also some cultural case studies. Obviously geared toward architectural use, ...
Sonic Experience: A Guide to Everyday Sounds by Jean-Francois Augoyard and Henri Torgue is an excellent book that explains many sonic experiences and acoustic phenomena by going into the philosophy, aesthetics, cultural context, and psychoacoustics of sound without going into too much detail about the physics or math.
Make your way to the local pet store. Talk to the owner / manager about what you need and why you need it; you will probably find them willing to help and interested in what you need the sounds for.
Also, try guinea pigs, hamsters and gerbils.
I have a bird caller, which consists of a wooden bead around a metal shaft - it's amazingly good for making a variety of bird chirps and squeaky noises. They are easy to pick up a outdoor type stores.
Not sure how mousey that would sound, but I'm happy to post a recording if you're interested.
Two resources to try:
Ann Krober at Sound Mountain. She oversees a vast library of sounds that may or may not include playful elephants.
The Macaulay Library. From their site:
The Macaulay Library is the world's largest and oldest scientific
archive of biodiversity audio and video recordings. Our mission is to
collect and preserve recordings of each ...
First of all, I think it would help to let us know which language the people are talking. Furthermore, if there's such a small group of people, is it really necessary to make it sound like a typical party? I tend to talk much softer when a party is quieter.
People behave differently in smaller groups, lower volume, lower pitch. It's not just reverb ...
I find a good understanding of acoustic principles a vital aspect for sound design, especially when it comes to setting sounds in different environments - difficult to do well unless you understand how sound waves move and interact with obstacles. I recommend Master Handbook of Acoustics to my students. Quit scientific, but gives some great descriptions of ...
Get one of those stools that you twist/spin to raise higher or lower - like a piano stool. One that is squeeky is easy to manipulate and I'm sure you can re-create a sound like that if you manipulate something like that with pitch shifting it up.
Otherwise, did you try searching Sound Dogs?
In contrast to how little sound they apparently make while walking, elephants have a pretty killer roar when unhappy - saw this video today and this was the first thread I thought of. Bone chilling.
Also think about other sounds an elephant might make -- flapping its ears, blowing water from its trunk. These things can be designed on your own (e.g. flapping bed sheets), without needing to go out and record an elephant.
