Four generations, in the order the canopy grew them, and each one is an organ rather than a feature. The first made a creature into a place, the second stopped the crowd choosing what it saw, the third made the signal stop lasting, and the fourth grew the choice inside the bird. The private lineage is the counter-current to the third: it evolved in the same decade, and it is the only branch here that grew by taking something away.
Epoch 1
The Profile Nest
2003–presenta Profile Nest, a Top-8 Crest, a Music Gland, HTML Feathers and a Comments Perch
The founding generation, and the mutation that made the whole species possible: a bird stopped being a voice in a shared room and became a place of its own. The Profile Nest gave every creature an address, the Top-8 Crest turned the flock into a visible ranking, the Music Gland made attraction audible, and HTML Feathers let a bird decide how it looked — the first time plumage was a decision rather than a trait. The Comments Perch is the organ the canopy has never been able to put down.
Behaviour · Loud, self-arranging and unstable: the generation that made identity something you build and then redecorate until it collapses.

Epoch 2
The Feed Eye
2004–2010a Newsfeed Eye, Identity Talons, Group Wings and an Ad Gland
The generation the crowd stopped choosing what it saw. A Newsfeed Eye reads every bird’s relationships and decides which songs reach it, Identity Talons anchor a bird to a real name instead of a handle, Group Wings let flocks form around anything at all, and the Ad Gland turned the flock’s attention into the first honest currency the canopy ever had. The constraint removed is the audience’s own discretion — after this generation, a flock is shown its canopy rather than finding it.
Behaviour · Territorial and algorithmic: it builds Social Meadows, and its reach is measured in how much of the meadow it decides.

Epoch 3
The Story
2010–2016Filter Feathers, a Story Gland, an Influencer Crest and Reels Wings
The generation the signal stopped lasting. A Story Gland makes a broadcast that is gone by morning, which removed the last reason to be careful; Filter Feathers made the appearance authoritative rather than the event; the Influencer Crest grew a single bird into a perch a whole flock watches; and Reels Wings let short-form flight travel the same currents as long-form storytelling. The constraint removed is the record — a canopy where nothing is kept is one where nothing can be checked.
Behaviour · Visual, curated and social: it builds Aesthetic Groves, where the plumage is the point and the song is evidence of it.

Epoch 4
The For-You Gland
2016–presenta For-You Gland, Loop Wings, a Remix Crest, Challenge Feathers, and — in the same decade — an End-to-End Gland
The youngest generation, and the one where the habitat became the algorithm. A For-You Gland reads an individual bird’s taste from its last few movements and assembles a canopy containing nothing else; Loop Wings make the same song repeat until it is not a choice to keep hearing it; the Remix Crest makes a signal something every other bird is invited to mutate; and Challenge Feathers trigger flock-wide behaviour on command. The same decade grew the counter-organ: an End-to-End Gland that makes a song unlistenable to anyone but its flock. One generation, two constitutions, and the canopy has not settled the argument.
Behaviour · Hyper-fast, viral and mutation-driven: it builds Viral Gardens, and it is the first generation whose members cannot see the same sky as each other.
