Critters II!

[Bhu]

(Meanwhile: do these sound about right?
Oread (Medium Fey):
Oreads possess the following racial traits.

+2 Dexterity, -2 Charisma.
Medium size.
An oread’s base land speed is 30 feet.
Low-light vision.
Weapon Proficiency: Oreads are automatically proficient with the dagger, shortbow, and composite shortbow.
+2 racial bonus on Listen, Search, Spot and Survival checks.
Energy resistance: Oreads have cold resistance 5.
Spell-like abilities: 1/day —snare, stone tell.
Automatic Languages: Common, Sylvan.
Favored Class: Ranger.

Do the SLA's use the default caster level? Also the spells are too powerful for first Level. I'd write that they are available 1/day when they are of appropriate hit dice. For example Stone Tell is a 6th Level Druid spell which would be castable as an 11th Level Druid. So it should be available to the Oread 1/day once they are 11 hit dice.
This goes for the other fey as well.

Napaia (Medium Fey):
Napaias possess the following racial traits.

+2 Wisdom, -2 Charisma.
Medium size.
A napaia’s base land speed is 30 feet.
Low-light vision.
Weapon Proficiency: Napaias are automatically proficient with the dagger, shortbow, and composite shortbow.
+2 racial bonus on Knowledge (nature), Move silently, Hide and Heal checks.
Damage reduction 5/fire.
Spell-like abilities: 1/day —tree stride, 1/day — speak with plants.
Automatic Languages: Common, Sylvan.
Favored Class: Druid.

Damage Reduction is only against physical damage, not energy. It'd need to be something other than Fire. Same with the Hyad below. Gimme a bit for the Thamnad. Do you want it as race or monster class?

Hyad (Medium Fey):
Hyads possess the following racial traits.

+2 Constitution, -2 Charisma.
Medium size.
A hyad’s base land speed is 30 feet.
A hyads base swim speed is 30 feet.
