I don't have the Raptorrians stats i front of me but to see if they are overpowered let’s compare them to other races:
DWARVES
• +2 Constitution, –2 Charisma.
• Medium: As Medium creatures, dwarves have no special bonuses or penalties due to their size.
• Dwarf base land speed is 20 feet. However, dwarves can move at this speed even when wearing medium or heavy armor or when carrying a medium or heavy load (unlike other creatures, whose speed is reduced in such situations).
• Darkvision: Dwarves can see in the dark up to 60 feet. Darkvision is black and white only, but it is otherwise like normal sight, and dwarves can function just fine with no light at all.
• Stonecunning: This ability grants a dwarf a +2 racial bonus on Search checks to notice unusual stonework, such as sliding walls, stonework traps, new construction (even when built to match the old), unsafe stone surfaces, shaky stone ceilings, and the like. Something that isn’t stone but that is disguised as stone also counts as unusual stonework. A dwarf who merely comes within 10 feet of unusual stonework can make a Search check as if he were actively searching, and a dwarf can use the Search skill to find stonework traps as a rogue can. A dwarf can also intuit depth, sensing his approximate depth underground as naturally as a human can sense which way is up.
• Weapon Familiarity: Dwarves may treat dwarven waraxes and dwarven urgroshes as martial weapons, rather than exotic weapons.
• Stability: A dwarf gains a +4 bonus on ability checks made to resist being bull rushed or tripped when standing on the ground (but not when climbing, flying, riding, or otherwise not standing firmly on the ground).
• +2 racial bonus on saving throws against poison.
• +2 racial bonus on saving throws against spells and spell-like effects.
• +1 racial bonus on attack rolls against orcs and goblinoids.
• +4 dodge bonus to Armor Class against monsters of the giant type. Any time a creature loses its Dexterity bonus (if any) to Armor Class, such as when it’s caught flat-footed, it loses its dodge bonus, too.
• +2 racial bonus on Appraise checks that are related to stone or metal items.
• +2 racial bonus on Craft checks that are related to stone or metal.
• Automatic Languages: Common and Dwarven. Bonus Languages: Giant, Gnome, Goblin, Orc, Terran, and Undercommon.
• Favored Class: Fighter. A multiclass dwarf ’s fighter class does not count when determining whether he takes an experience point penalty for multiclassing
ELVES
• +2 Dexterity, –2 Constitution.
• Medium: As Medium creatures, elves have no special bonuses or penalties due to their size.
• Elf base land speed is 30 feet.
• Immunity to magic sleep effects, and a +2 racial saving throw bonus against enchantment spells or effects.
• Low-Light Vision: An elf can see twice as far as a human in starlight, moonlight, torchlight, and similar conditions of poor illumination. She retains the ability to distinguish color and detail under these conditions.
• Weapon Proficiency: Elves receive the Martial Weapon Proficiency feats for the longsword, rapier, longbow (including composite longbow), and shortbow (including composite shortbow) as bonus feats.
• +2 racial bonus on Listen, Search, and Spot checks. An elf who merely passes within 5 feet of a secret or concealed door is entitled to a Search check to notice it as if she were actively looking for it.
• Automatic Languages: Common and Elven. Bonus Languages: Draconic, Gnoll, Gnome, Goblin, Orc, and Sylvan.
• Favored Class: Wizard. A multiclass elf ’s wizard class does not count when determining whether she takes an experience point penalty for multiclassing.
GNOMES
• +2 Constitution, –2 Strength.
• Small: As a Small creature, a gnome gains a +1 size bonus to Armor Class, a +1 size bonus on attack rolls, and a +4 size bonus on Hide checks, but he uses smaller weapons than humans use, and his lifting and carrying limits are three-quarters of those of a Medium character.
• Gnome base land speed is 20 feet.
• Low-Light Vision: A gnome can see twice as far as a human in starlight, moonlight, torchlight, and similar conditions of poor illumination. He retains the ability to distinguish color and detail under these conditions.
• Weapon Familiarity: Gnomes may treat gnome hooked hammers as martial weapons rather than exotic weapons.
• +2 racial bonus on saving throws against illusions.
• Add +1 to the Difficulty Class for all saving throws against illusion spells cast by gnomes. This adjustment stacks with those from similar effects.
• +1 racial bonus on attack rolls against kobolds and goblinoids.
• +4 dodge bonus to Armor Class against monsters of the giant type. Any time a creature loses its Dexterity bonus (if any) to Armor Class, such as when it’s caught flat-footed, it loses its dodge bonus, too.
• +2 racial bonus on Listen checks.
• +2 racial bonus on Craft (alchemy) checks.
• Automatic Languages: Common and Gnome. Bonus Languages: Draconic, Dwarven, Elven, Giant, Goblin, and Orc. In addition, a gnome can speak with a burrowing mammal (a badger, fox, rabbit, or the like, see below). This ability is innate to gnomes. See the speak with animals spell description.
• Spell-Like Abilities: 1/day—speak with animals (burrowing mammal only, duration 1 minute). A gnome with a Charisma score of at least 10 also has the following spell-like abilities: 1/day—dancing lights, ghost sound, prestidigitation. Caster level 1st; save DC 10 + gnome’s Cha modifier + spell level.
• Favored Class: Bard. A multiclass gnome’s bard class does not count when determining whether he takes an experience point penalty.
By 10th level any race can fly (take 5 levels of wizard and gain the fly spell) so it really isn;t that big an advantage by then.
Dwarves' saving throw bonuses come into play a heck of lot more often than do a bonus to jump. They also aren't slowed down by any armor (love that 3.5 mod).
