Wild Draco Stryx are temporary partners when mates are chosen, and will stay together until their eggs have hatched and their offspring grow large enough to leave the nest. Monogamy, however, is not uncommon, when two mates are well suited and feel no compulsion to seek out another. Domesticated Stryx, unless allowed to pair-bond by their riders, are mainly non-monogamous and kept apart after mating has occurred.

During the mating season, females will become highly irritable and defensive, while males become extremely territorial and aggressive. This is a dangerous time for Stryx, who will compete fiercely for mates, if allowed. Therefor, it is integral that males, especially, be kept apart during the breeding season. Unless they are very well trained, and the bond with their rider is strong enough to override their initial instincts, bloody fights can break out and, in a worst case scenario, lead to death. Females, however, are more of a worry directly to their riders, as they will often become obstinate, and refuse to leave their nests, and may lash out if provoked.

Inbreeding can have catastrophic results, such as stillbirth, crippled/malformed wings, brittle bones, blindness, and infertility. Chances for producing a healthy clutch out of inbred parents are low.

The mating season generally lasts 1-4 weeks in winter, and eggs are laid in spring and summer, and might take until fall to hatch. Once hatched, a baby Stryx will not leave its mother until the following spring, when it is large enough to begin fending for itself, and clears out of the nest to make room for another clutch of eggs to be laid.

Males and females are both limited to 5 breeding slots initially. However, there are art goals available in the Bonuses section, detailing how you can obtain extra breeding slots when the initial 5 have been used up.


While in the nest, the diet of a baby Stryx consists of partially digested meat, fed to them by their parents, or alternatively can be fed small cuts of meat or whole fish fed by human handlers. Some riders will also collect and crush up insects, mixing them with meat, milk and blood (cow, goat, etc.) until a high protein/high fat mash is made. This is especially useful for hatchlings who are the "runts" of the clutch, and promotes a slightly faster rate of growth so that they can catch up to their siblings.

Adolescent Stryx who are large enough and coordinated enough to begin hunting for themselves will target prey animals such as rabbits, moles, snakes, and birds. Some riders will continue to feed them the afforementioned "mash" if they are slow learners, or prey is scarce in the area.

By adulthood, Stryx are usually highly successful hunters/fishers, targeting larger prey wherever it's available. Tuna, swordfish, sharks and other large fish species are usually a favorite food source for adults, who seem to take a great deal of enjoyment in the activity of fishing in general. However, they are less successful in scoring kills in the water compared to on land.


Draco Stryx can be described as bird-like, flying theropods, with ancestry tied back to dinosaurs. It is clear that they convergently evolved alongside birds, and so share many similarities since they both share a common ancestor. They share most of their similarities with the raptor family, or "birds of prey," as well as dinosaurian raptors, like Deinonychus and Archaeopteryx. Sapeornis also serves as a useful skeletal reference to the bone structures of Draco Stryx.

Draco Stryx have long, sharp, conical teeth toward the back of their beaks. Their mouths are arranged so that the curved frontside of the beak is meant for gripping, while the primary function of the teeth is to shred and tear. However, when fishing, Stryx have been seen dipping their heads into the water and leaving their mouths agape, undulating the tongue to catch the attention of fish.  If a fish swims into their jaws, these teeth act as skewers, effectively impaling and incapacitating the fish.

These teeth are also unique in that their anchor-points are flexible, allowing a Stryx to "fold back" or "sheath" these dangerous teeth, especially useful when feeding their young, or play-fighting, avoiding inflicting serious injury.

Biorhythm and Boosts:

All Draco Stryx are born with a natural biorhythm that dictates whether they are diurnal (active in the day), crepuscular (active at dawn/dusk), or nocturnal (active at night). 

Diurnal dragons are most active during the day, and receive a +1AP bonus to any pictures drawn in a daytime setting. They display the Dawn background on Import references.

Crepuscular dragons are most active at dawn and dusk, and receive a +1AP bonus to any pictures drawn in a dawn or dusk setting. They display the Dusk background on Import references.

Nocturnal dragons are most active at night, and receive a +1AP bonus to any pictures drawn in a nighttime setting. They display the Night background on Import references.

When a Nocturnal and Diurnal Stryx are bred, their hatchlings will be Crepuscular. However, when two parents with the same biorhythms are bred, their hatchlings are guaranteed to inherit the same alignment.

How do u get one cuz i would really like a Chiros
EyeOfGalyx Featured By Owner Jun 26, 2019
you can either get a chiro through the adoption centre if there is any, or if anyone is selling chiro pups. Chiro pups are a bit more uncommon cause of their clutch size so don't be afraid to get a bird or runner stryx for your first stryx to get a feel of the ARPG ~Alri
ScorpionNinjaGirl Featured By Owner Jun 26, 2019  Hobbyist General Artist
Ok thanks! by the way the adoption is kind of confusing. can you make you own and see if they get approval? 
EyeOfGalyx Featured By Owner Jul 1, 2019
While you can not make your own stryx without a geno (basically baby stryx, just in written form), however you can draft up a design if you are unsure if you want a specific geno. To adopt, you just comment with a geno of your choice and the geno is transferred to you upon approval and you can design the geno and get it approved.

I wonder, are baby stryx naked when they hatch? (I know that normal birds are, but those are magical creatures)

I wanted to make a little short comic how my rider found her stryx, but this would mean to draw a new born stryx
Yoshitsune06-15 Featured By Owner Nov 24, 2018  Hobbyist General Artist
I have a question I haven't found yet: did the stryx speak like other ARPG creatures maybe with telepathy or they don't speak like humanoids (with telepathy or not) and only emits noises typical of their own specie? ^^
PalieFox Featured By Owner Dec 12, 2018  Student Digital Artist
-Not an admin,

As far as I've understood they don't speak the same language and just make usual bird noises, 
but like most things with stryx, it's up to you, the rules on world building are really quite flexible~

Hope this answers your question ^^

I had a quick question about Lycans. Can they only breed with other Lycans, or can they breed with Chiros as well?
dragonmissy Featured By Owner Apr 4, 2018  Hobbyist Artist
They can breed  with lycans and chiros

Thank you <3

Question: Will there be Runners based off of bigger theropod dinosaurs? If not, I have one simple image for you:

Dragonhawk theropod with long powerful arms equipped with vicious hooked talons.

Starting to see how that would be awesome?

What is the general Wingspan and weight of a tyto?
kyrraven Featured By Owner Apr 2, 2017
I have a couple of Chiro specific questions...

1- Do chiros perch like birds, hang upside-down like bats, or both?

2- Is it acceptable to draw them with features like a flying fox?

3- Are there plans to have sub-species as with the avian stryx?
DamienRhys Featured By Owner May 20, 2017  Hobbyist
I can't answer the first one of these, but as for the other two, I believe they are a bit related. There has been some discussion for eventual expansion and bats that are more like flying foxes and fruit bats, but there is nothing concrete as of now. On that note, you're allowed to depict your Stryx however you like so long as they are recognizable~
Lediblock2 Featured By Owner Mar 15, 2017
You know, I've been wondering - will there be any more... reptilian dragons?
red-anteater Featured By Owner Mar 3, 2017
will the raptor and chiro be added to that handy height chart in the future? :'3c
imagining sized with just the numbers is kinda hard <'y
Winterfaux Featured By Owner Mar 20, 2017  Student Digital Artist
+1 I need visual reference because what are numbers
Shadzerios Featured By Owner Mar 1, 2017  Hobbyist Digital Artist
What are the average wingspan, weight and height for each subspecies?

I would be interested to know these facts for better character creation. If I remember right there was these facts once but they have suddenly disappeared, which I'm very sad about. I wish to recall at least tyto, corva, harpia and gryph info since those were ones that once located in this journal. I don't think Chiros were published after "newest import style" was change.
Direwolfqueen Featured By Owner Feb 14, 2017  Hobbyist Traditional Artist
Do Stryx make noises Within a similar range of the type of bird they are based off of?
Northern-Winter Featured By Owner Feb 3, 2017  Hobbyist General Artist
if a diurnal and a crepuscluar bird were both in a picture at dawn, would they both get the bonus?
FRAT-RAT Featured By Owner Nov 6, 2016  Hobbyist Digital Artist
and all of them are precious, precious birds.

When will the Chiros' infos be added?
EyeOfGalyx Featured By Owner Oct 15, 2016
Chiro's info has already been added. They were added when chiros where first mentioned, However they haven't been added to the size chart. ~Alriandi
Guduler Featured By Owner Oct 16, 2016  Hobbyist Digital Artist
Ah yes the size chart is what I meant, sorry :'D Since I'm drawing something for the chase I wanted to know how big they were!
ashenantlers Featured By Owner Jan 31, 2017  Professional Digital Artist
They're the same size as Tytos :)

thanks! :D

so ive seen mention of this in other places, but no explanation
so I guess it cant hurt ot ask her since it regards the species
How do you know if you gryph has a bald head? Is it a trait or do certain types (Ie common) naturally come with bald heads?
EyeOfGalyx Featured By Owner Oct 10, 2016
It's completely up to you if you'd like your gryph to have a bald head! c:
Common and silken both come with the option!

Question on breeding slots... assuming you never do anything to gain more than the initial five, is that five per season, or five for the stryx's life?
EyeOfGalyx Featured By Owner Sep 16, 2016
The 5 slots a stryx gets once they unlock their EoG is for life, but they do get another 10 slots ontop of that when they get to Alpha level, 15 more slots when they get to Legendary rank and then unlimited slots when they get to ascended rank. However, you can only breed 3 times (4 if you are a career breeder) and allowed 2 splits per month.
red-anteater Featured By Owner Sep 6, 2016
whats is like the lifespan of these creatures? :0c
I dunno if I missed it or its not stated.

cuz I never rly know what age to give my stryx, and like what is assumed old or young
EyeOfGalyx Featured By Owner Sep 6, 2016
There is no official lifespan, though sexual maturity is reached at 2 years of age. Other than that, you should be able to do what fits your lore.
red-anteater Featured By Owner Sep 6, 2016
ooh alrighty :0c
I was never sure what would be concidered an "old" stryx, so I gues I'll just make stuf up then B'D
alarmed-dingoes Featured By Owner Aug 22, 2016  Hobbyist General Artist
OH MAN Hawk Stryx! Super pumped!
Areetala Featured By Owner Aug 19, 2016  Hobbyist General Artist
ooh I didn't notice the hawk stryx were added! They look so cool! Do you know when they will be released? Will there be an event like the harpia hunt and gryph attack?
ChaokiEvery Featured By Owner Aug 20, 2016  Student Filmographer
I think it's the misterious eggs that you own with gryph feathers :)
