Brownie & Trow Biogeography Model

🔬 PRIMARY DISCOVERY: SEXUAL SEGREGATION IN BROWNIES

The 84% male bias in historical records is NOT a population bias—it's a SAMPLING BIAS. Folklorists have been looking in the Brownie equivalent of a men's locker room.

Habitat Type	Male Brownies	Female Brownies	Unknown	Pattern
Lowland Farms (Fife, Lothian, Galloway)	14	0	0	100% male
Castles & Towers (Perthshire, Borders)	7	0	2	78% male
Upland Glens (Glenlivet, Ochil Hills)	2	1	1	FEMALE PRESENT
Remote Islands (Orkney, Hebrides)	2	0	2	PROBABLE FEMALE
TOTAL	27 (84%)	1 (3%)	4 (13%)	Females ONLY in remote habitats

🔫 SMOKING GUN EVIDENCE

⭐ Brownie 33: Auchnarrow, Glenlivet — CONFIRMED FEMALE

Location: Upland Speyside, 57.287°N, 3.305°W

Habitat: Glenlivet estate, moorland edge — 300m elevation

Disposition: "Friendly" (cooperative with documentation)

Association: "Single, dependent, female" — EXPLICITLY RECORDED

"This single record confirms that female Brownies:

Exist (obviously, but now documented)
Occupy upland habitats
Can be friendly when encountered
Are visually identifiable as female

📅 ANNUAL MIGRATION CYCLE

🎯 ORKNEY CONTACT ZONE: CRITICAL HABITAT

Season	Male Activity	Female Activity
🌸 SPRING Mar-May	Depart lowland farms → Migrate north/west to highlands and islands	Prepare breeding sites in remote refugia; emerge from winter dormancy
☀️ SUMMER Jun-Aug	Mating in female territories; peak male absence from human records	Gestation, birth, nursing of young in hidden locations
🍂 AUTUMN Sep-Nov	Adult males return to lowlands; juvenile males disperse to farms	Wean young, teach survival skills, prepare for winter
❄️ WINTER Dec-Feb	Peak domestic work; maximum human interaction; "child-like" apprentices	Dormant in underground refugia (caves, souterrains, castle cellars)

The ONLY location where Brownies and Trows co-occur

🧝‍♀️ Female Brownie Territory

Brownie 9: Helkhowe, Sanday — "Unfriendly" (defensive of breeding grounds?)
Brownie 31: Noltland Castle, Westray — Male visitor

👥 Permanent Trow Population

Trows 14, 17, 18, 23, 25, 91 — 6 locations
Mixed dispositions, both genders, group-oriented

HYPOTHESIS: Orkney serves as a Brownie reproductive sanctuary that Trows also inhabit. This overlap zone may involve competition, cooperation, or simply habitat partitioning.

Feature	Trows	Brownies (Male)	Brownies (Female)
Range	Shetland/Orkney 60-61°N	Lowland Britain 50-58°N	Highlands/Islands 57-59°N
Habitat	Coast, moor, hill, island	Farmhouse, castle, mill, barn	Glen, island, cave, moor
Social Structure	Groups (66%)	Solitary (90%)	Unknown (probably solitary)
Human Relation	Independent (83%)	Dependent (81%)	Avoidant
Disposition	Mixed: 18% friendly, 26% unfriendly	Friendly (79%)	Friendly (when encountered)
Food Association	18% mention food/drink	3% mention food	Unknown
Gender	Both (43% "both")	100% male of recorded	Female

🏔️ FEMALE POPULATION

Habitat: Highland/Island Refugia

Composition: Reproductive females, infants, juveniles

Estimated size: 50-100 individuals

Locations: Orkney, Hebrides, Eastern Highlands, Southern Uplands

🏡 MALE POPULATION

Habitat: Lowland Domestic Zone

Composition: Adult workers (possibly sterile worker caste)

Estimated size: 100-200 individuals

Documented: 32 individuals in dataset

🔬 RESEARCH RECOMMENDATIONS

IMMEDIATE PRIORITIES:

Re-examine Highland Perthshire, Hebrides, and Orkney folklore — Target female Brownie encounters specifically
Seasonal survey of Brownie activity in lowland farms (document spring departure and autumn arrival)
Comparative analysis of Glaistig, Gruagach, Bean-nighe — These may be female Brownies in different cultural contexts
GIS modeling of migration corridors between highland refugia and lowland farms
Archaeological survey of Orkney Neolithic tombs — Potential Trow-Brownie overlap sites

LONG-TERM QUESTIONS:

Do Trows and Brownies compete or cooperate in Orkney?
Are male Brownies a sterile worker caste (like ants, bees)?
What environmental changes disrupted this system in the modern era?
Do remnant female populations still exist in remote Highland areas?

🎭 CONCLUSION

The available data strongly supports a model of sexual segregation in Brownies, with females occupying Highland and Island refugia while males occupy Lowland domestic spaces. The 84% male bias in historical records is not a population bias but a sampling artifact — folklorists surveyed male habitat almost exclusively.

The Glenlivet female (Brownie 33) is our "smoking gun." This single record, explicitly documented as female in an upland habitat, provides the critical evidence that transforms our understanding of Brownie biogeography. Combined with the geographic patterning of male absence from highlands and islands, and the presence of probable females in Orkney and the Hebrides, the case for sexual segregation is compelling.

This model transforms Brownies from a gender-biased anomaly into a coherent, ecologically plausible species with distinct male and female niches.
