Bird stats

The nine stats

Source: scripts/bird_data.gd, scripts/loft.gd. The older name for Recovery was Vitality; old saves are converted automatically.

Where each stat counts

Speed

• Races: weighs 1 - km/600 of the ability score. That is 83% of the speed-or-stamina part in the 100 km Club Sprint and 0% in the 600 km Classic. See race ability.
• Roller Display: 15% of a bird's trick skill.
• Hawk: a lower speed makes a bird more likely to be picked (free roam hawk). A bird with Speed and Power both above 70 guards the flock and cuts the hawk's catch chance by 25%.
• Selling: counts in the average and in the best-stat part of the price.

Stamina

• Races: weighs km/600 (capped at 1) of the ability score. The 600 km Classic is all stamina.
• Flying Meet: 50% of Timed Flight, 55% of Endurance Marathon, 35% of the Altitude Cup altitude score.
• Lure: half of the Anchor and High flyer strength.
• Training: goes up by tosses and by free roam, up to its potential.

Navigation

• Races: adds 0.45 x NAV to the ability of every race, short or long.
• Risk: the loss chance of a race is multiplied by 1.6 - NAV/100. Training tosses use 1.5 - NAV/100. In tournaments it counts 40% of "homing" (with Intelligence 30% and bond 30%).
• Lost birds: the chance that an astray bird ever finds its way home is 40% + 20% x NAV/100 (lost birds).
• Hawk: low Navigation raises both the pick weight and the catch chance (hawk).

Recovery

• Races: adds 0.15 x REC to the ability, and the loss chance is also multiplied by 1.25 - REC/200.
• Tournaments: 15% of Timed Flight, 20% of Endurance, 15% of the Altitude score; the same loss factor; 25% of a show bird's Condition mark.
• Lure: half of the Anchor strength.

Power

• Races: adds 0.2 x PWR to the ability.
• Flying Meet: 10% of Timed Flight and Endurance, 25% of the Altitude score.
• Hawk: with Speed above 70 it makes an escort bird.

Intelligence

• Bond: adds INT/20 bond points every day (a bird with INT 80 gains 4 extra points a day).
• Tournaments: "discipline" is the average of Intelligence and Temperament (25% of Timed Flight, 15% of Endurance); 15% of the Altitude score; 40% of the landing mark; 25% of Roller trick skill; 30% of a show bird's Posture.
• Wild strays: a smarter stray is warier in the Trap (30% of its Intelligence adds to wariness).

Agility

• Roller Display: 40% of trick skill. Lure: half of the Roller strength.

Temperament

• Bond: adds (TMP - 50)/25 bond points a day, so a calm bird (TMP 75) gains 1 more and a nervous one (TMP 25) loses 1.
• Tournaments: half of "discipline", 10% of the Altitude score, 30% of the landing mark, 20% of Roller skill, 40% of a show bird's Posture, half of the Show lure strength.

Fertility

• Chance that an egg is fertile: 88% + (FER sire + FER dam - 100)/400. See breeding. Rarer racing lines are harder to breed.

Starting stats

Every bird belongs to one or two breeds (a "line mix"). A new shop bird is a main breed at 100%, 90% or 75% (equal chance), and the rest is another breed of the same class.

Examples: a 100% Janssen has base speed 76, so its speed is between 68 and 84. A bird bred from two parents uses a different rule, see how chicks inherit stats. A wild stray has 90% of the stats a shop bird of that breed would have.

Potential: the training ceiling

Only Navigation and Stamina grow during a bird's life, and each stops at its potential:

A bird already above its potential (a lucky roll, or a good parent) never loses points; training just does nothing for that stat. A bird's age does not change its stats. All other stats (speed, recovery, power, intelligence, agility, temperament, fertility) are fixed for life, so choose them by buying or breeding.

Training: tosses and free roam

A bird must be a batcher (bond 100%) to be tossed or sent outside. Both ways train the same two stats, Navigation and Stamina.

Training tosses

Once per bird per day you can toss it 1, 5 or 20 km. Each toss has a loss chance of base x (1.5 - NAV/100), clamped between 0.5% and 50%. If the bird comes home, Navigation and Stamina each gain a random amount in the range shown (never above potential).

A lost bird is always "astray" (a toss never kills a bird); see lost birds. Racing a bird also counts as its toss for the day.

Free roam

Birds flying outside train slowly and for free. Every 15 real seconds (not game time) each roaming bird rolls once for Navigation and once for Stamina. Each roll succeeds with 30%, or 40% when 3 or more birds are outside, and adds +1 (up to potential). Details are on the free roam page.

Breed traits in races

Each breed has a trait. The race is one speed number, so the code averages a trait that works on part of the race over the whole race. The text in the shop and bird details can read bigger than the real effect; the table shows what the race code does (Races.trait_effects). "Short" means 200 km or less; "long" means 350 km or more.

The flying and fancy traits work in the tournaments; the Sky Marathon, Cloud Climber and similar traits do nothing in a race.
