About AviLedger
AviLedger is record-keeping software for bird breeders, built and supported by Elcolynx, an independent software studio registered in South Africa.
A breeding record is not a spreadsheet problem. Hatch dates depend on species, a pairing decision depends on what is behind both birds, and a permit matters most on the day it expires. AviLedger holds all of it in one place, on the phone in your pocket in the birdroom and on the desktop where you plan.

How we build it
Built for the birdroom
It works offline, because signal in an aviary is not a given, and syncs when you are back in range.
Species-specific, not generic
Incubation periods, weaning weights and mutation inheritance differ by species, so the app treats them that way.

Where the species data comes from
Taxonomy, families, orders and conservation status come from AviList v2025, the unified global bird checklist agreed between Clements/eBird, the IOC, BirdLife International and Howard & Moore. AviList is used under the Creative Commons Attribution 4.0 licence.
We have changed it in one way, on purpose: a checklist settles on one English name per species, and aviculture often uses another. A Rose-ringed Parakeet is an Indian Ringneck to the people keeping them. So the names breeders use are carried alongside the ones AviList settled on, and searching for either finds the bird.
CITES appendices come from the Checklist of CITES Species, compiled by UNEP-WCMC for the CITES Secretariat. Where a species has no record we say so rather than reading silence as "not listed".
Incubation periods, ring sizes and weaning weights are not in any checklist. Those are AviLedger's own, gathered with breeders, and shown only where we have them.
