Successful nesting by 2 endangered Hawaiian waterbird species in a restored Indigenous wetland agroecosystem/Anidacion exitosa de 2 especies de aves acuaticas hawaianas en peligro en un agroecosistema indigena restaurado

The Hawaiian Stilt (Himantopus mexicanus kmidseni) and Hawaiian Gallinule (Gallinula galeata sandvicensis) are federally endangered waterbirds endemic to the Hawaiian Islands. Both species are conservation-reliant; their population persistence is dependent on invasive predator control and removal of invasive plants that degrade habitat. We present observations of successful nesting by one Hawaiian Stilt pair and one Hawaiian Gallinule pair at a site managed within an adaptive Indigenous agroecological framework on the island of O'ahu, Fiawai'i. The Hawaiian Stilt nest, found in February 2019, contained 4 eggs and produced 3 hatchlings, 2 of which were banded and monitored after hatching. The Hawaiian Gallinule nest, found in February 2020, contained 6 eggs and produced 5 hatchlings. Although no individuals were banded from this nest, 2 adults and 2 hatchlings were continuously observed in the nesting area after the eggs hatched. Lo 7 kalo Hawaiian wetland agroecosystems centered around the cultivation of kalo (taro; Colocasia esculenta), have the potential to expand Hawaiian waterbird habitat beyond state and federal protected areas. We are aware of unpublished accounts of Hawaiian waterbirds nesting in commercially fanned lo 7 kalo, but until now, there have been no previously published accounts of native waterbirds breeding in lo 7 kalo managed as Indigenous agroecosystems.

(Spanish)--La monjita Himantopus mexicanius knudseni y la gallareta Gallimila galeata sarulvicensis son aves acuaticas fcderalmente en peligro endemicas a las islas hawaianas. Ambas especies dcpenden de acciones de conservacion; la persistencia de sus poblaciones depende del control de depredadores invasores y de la remocion de plantas invasoras que dcgradan sus habitats. Presentamos observaciones de anidacion exitosa de una pareja de monjita y una de gallareta en un sitio mancjado mediante practicas indigenas agroecologieas en la isla de O'ahu. Hawai. El nido de la monita, encontrado en febrero de 2019, contenia 4 huevos y produjo 3 polluelos, 2 de los cuales fueron anillados y monitoreados despues de eclosionar. Aunque ningun individuo de estc nido fue anillado. 2 adultos y 2 polluelos fueron continuamente observados en el area del nido despues de que los huevos eclosionaron. Los agroeeosistemas de humedales hawaianos (l'oi) tienen el poteneial de expandir el habitat de las aves acuaticas hawaianas mas alia de las areas protegidas estatales y federales. Sabemos que hay reportes de aves acuaticas hawaianas sin publiear en loi comercialmente cultivados. pero hasta ahora no habia reportes previos publicados de aves acuaticas nativas en l'oi bajo mancjo como agroeeosistemas indigenas.
