The extinct night-heron from Bermuda has been described as a different species, and it seens that survived until the XVIIth century. A New Species of Night-heron (Ardeidae: Nyctanassa) from Quaternary Deposits on Bermuda Storrs L. Olson, and David B. Wingate Proceedings of the Biological Society of Washington, 119 (2): 326-337. ABSTRACT Nyctanassa carcinocatactes is described from Pleistocene and Holocene cave and pond deposits on the island of Bermuda. It is most similar to the Yellow-crowned Night-Heron N. violacea but differs in having a shorter and much heavier bill, a much more massive cranium, and more robust hindlimbs. Early historical accounts contain descriptions of what is undoubtedly this species, which was presumably exterminated subsequent to human colonization of Bermuda. The cranial and hindlimb specializations of the new species appear to be adaptations for feeding terrestrially on land crabs. www.bioone.org/perlserv/?request=get-document&doi=10.2988%2F0006-324X(2006)119%5B326%3AANSONA%5D2.0.CO%3B2&ct= 1 |

The Bermuda Night Heron (Nyctanassa carcinocatactes) is an extinct heron species from Bermuda. It is sometimes assigned to the genus Nycticorax. It was first described in 2006 by Storrs L. Olson and David B. Wingate from subfossil material found in the Pleistocene and Holocene deposits in caves and ponds of Bermuda. Its anatomy was rather similar to its next living relative, the Yellow-crowned Night Heron (Nyctanassa violacea) but it had a heavier bill, a more massive skull and more robust hindlimbs. The specialization of the bill and the hindlimbs showed that it was apparently adapted to the feeding on land crabs. There are also early historian reports referring to that species. It became possibly extinct due to the settlement of the Bermuda islands in the 17th century. en.wikipedia.org/wiki/Bermuda_Night_Heron |

Hello!
"There are also early historian reports referring to that species."
Do You know some of these contemporaneous reports where I could find some notes about this species?

Osteological and historical data on extinct island night herons (Aves: Ardeidae), with special reference to Ascension Island, the Mascarenes and Bonin Islands​ Abstract​ Night herons of the genus Nycticorax and Nyctanassa are adept island colonisers, occurring on a number of oceanic islands and island archipelagos. Continental species and those inhabiting large islands are generally not considered threatened, whereas night herons restricted to small, oceanic islands are particularly vulnerable to human interference. As a result, six out of nine described species and one subspecies, all derived from Nycticorax nycticorax, Nycticorax caledonicus or Nyctanassa violacea, are now extinct whereas a further three extinct species await description. The extinct island endemics generally exhibit morphological adaptations to an insular environment and diet, such as an increase or decrease in size, robust jaws and legs, and smaller wings with associated reduced flying ability than founding stock. Here I present an osteological comparison along with historical descriptions of the extinct, oceanic island night herons, with special reference to the Mascarene and Ascension fossil species, and Bonin Island subspecies, and show the degree of morphological changes between the founding and island taxa. I further discuss the reasons why they became extinct. www.sciencedirect.com/science/article/pii/S0016699523000591?via%3Dihub |
