Hookbeak
Beast -- Tiny (standard) / Small (pack variant) -- Open transitional terrain, settlement periphery, ruin upper levels, highland scrub
The pack variants nest differently from the standard birds -- not individually but in loose aggregations on elevated structures, using the height as a launch platform rather than just a perch. They coordinate around prey without coordinating: each bird is tracking the same target individually and the result looks like planning because it is geometrically similar to planning. I have watched them work a route-clearing operation on the ridgeline above our camp for three days. They are very good at what they do. I am glad they are small.

Ecology
The Hookbeak is the standard small-to-medium aerial predator in open terrain -- fast, sharp-eyed, and built entirely around the dive strike and the grip that follows. The name comes from the recurved anterior edge of the beak, which functions both as a lock on small prey and as a tear implement for processing larger kills. Standard Hookbeaks are common throughout open and transitional terrain, individually nonthreatening to anything larger than a rodent, and present in sufficient density that their absence from an area is a more notable signal than their presence.
The pack variant -- larger-bodied, more aggressive, with Pack Tactics and a developed coordination pattern around prey -- occupies elevated structures and open ridge terrain in family groups of three to eight. The Pack Tactics that characterize their hunting behavior is emergent in the same way as the Bladefin's: each bird is attacking from a separate vector, not executing a planned flanking maneuver, but the effect of multiple strike vectors is tactically equivalent to planning. The Pack Tactics advantage on attack rolls reflects that distributed-vector reality.
Both variants have Keen Sight -- the visual acuity of small raptors is among the highest documented in the fauna record, exceeding any human-baseline sensor by a wide margin in standard daylight conditions. A Hookbeak perched at altitude on a ruin structure can track ground-level movement that the party cannot detect at distance, which makes them useful as passive surveillance indicators: a cluster of Hookbeaks whose attention is focused in a specific direction has noticed something in that direction worth noticing.
The Miasm interaction is minimal and behavioral. Standard Hookbeaks are slightly more active in moderate-saturation zones; pack variants near high-saturation ruin structures develop a marginally elevated aggression threshold. Neither effect is tactically significant, but experienced guides read the behavioral pattern of Hookbeak populations in an area as one more substrate-state indicator alongside the rest of the ambient fauna record.

Encounter use
Standard Hookbeaks are environmental texture and passive surveillance indicators, not encounters. Use their attention to point at things. A single pack variant harassing a character over a kill is a nuisance that the character can resolve by leaving the kill. A family group of six pack variants protecting a nest site on a ruin structure that the party needs to access is a real encounter: Pack Tactics on six birds attacking simultaneously is meaningful Advantage applied by animals that fly out of melee range between attacks. The geometry of attacking birds that can approach from any angle, hit, and retreat to 30 feet of altitude before the character's next turn limits what melee-focused parties can do. Chase them off or use area effects. Individual attacks from birds at CR 1/8 are not dangerous; the accumulation is.
Salvage
Hookbeak primaries are shorter than Strikewing primaries but aerodynamically consistent -- useful fletching for light arrows and bolts where the reduced shaft length is not a constraint. The talons of pack variants are used as fine piercing instruments in engraving and surgical contexts. The eye tissue has the same high visual-band sensitivity as the Strikewing, in smaller quantity; the research applications are identical. In settlement communities, trained juvenile standard Hookbeaks are kept as vermin-control animals and, occasionally, as short-range message carriers between points with line of sight. The training is difficult and the animals are uncooperative, which limits the practice to specialists with time and tolerance for the process.
