The Venom Hawk: simple Animal->Magical Beast template (Advice)

[Ninjaxenomorph]

So, in my upcoming campaign taking place on a flying city, I had an idea for a local creature called a venom hawk. Basically a poisonous bird of prey, but they also have a connection to a mysterious and secretive assassin-cult. My original idea was modifying a hawk, but then I thought about how awesome it would be if I made a Roc-sized venom hawk... so I had the idea to turn it into a simple template! Note that this is for Pathfinder, but I'm sure the template will apply to 3.5 fine.

Venom Hawk

"Venom Hawk" is an inherited or acquired template that can be added to any creature of the Animal type with a flight speed. A venom hawk retains the base creature's statistics and special abilities except as noted here.

CR: Same as base creature +1

Type: The creature's type changes to Magical Beast. All HD changed to d10s. Do not change skills, saves, or BAB.

Senses: the creature gains Darkvision 60ft.

Movement: Reduce flight speed by 10ft, but improve flight maneuverability by one step.

Attacks: If the creature did not already have one, it gains a bite attack appropriate for its size. This bite attack is augmented by poison (see below)

Special Abilities: The creature gains the following special ability:

Poison (Ex) Bite-injury; save Fort DC 12+half the creatures HD+ Con modifier, frequency 1/round for 5 rounds, effect 1d4 Con, cure 2 consecutive saves

Feats: The creature gains Ability Focus: Poison as a bonus feat.

Abilities: Str+2, Con+4

And finally, for as much my use as others, an example:

Movement: Reduce flight speed by 10 ft., but improve flight maneuverability by one step.

I think this needs a minimum to be useful. No less than 30 feet perhaps.

Well, what birds are there with a flight speed less than 10? I basically added that because I imagine them as slightly ponderous and slow compared to other birds of prey..

[Debihuman]

1. Yes. Seagulls and chickens have fly speeds of 10 feet (or less) in some homebrews. Not sure if either is official since I don't have any books at the moment.

2. A creature with a 0 fly speed cannot fly.

3. 10 feet could be minimum but still makes this unwieldy. This should be a template for creatures who can fly at least 30 feet or more.

In Pathfinder, the system I'm using, seagulls use raven stats (40ft fly), and chickens have a fly speed of 20.

And I'm not making venom chickens.
