Of 2,332 young Redheads(Nyroca americana (Eyton)), banded in northern Utah in 1929, 1930 and 1931 there were 357 returns, all shot by sportsmen. The northward dispersionin fall is well illus- trated by September and October returns from Montana, Wyoming, North Dakota, South Dakota and Idaho. Although migration may begin early, many young remain in the breeding grounds until October. The returns show the principal wintering grounds for the Utah birds to be the Salton Sea region of southernCalifornia and the lower coast of Texas from Corpus Christi to Mexico. Eighty-sevenpercent of the birds taken were less than one year old; 10.6 percent were second-yearbirds, and two percent were third year or older. This ratio prompts the author to assumelogically that the first year is the critical one in the life of the bird insofar as shooting is concerned. -

The triumphs, challenges and failures of young North Island brown kiwi (Apteryx mantelli): a study of behaviour, growth, dispersal and mortality Stephanie Walden A thesis in partial fulfilment of the requirements for the degree of Master of Science in Zoology at Massey University, Palmerston North, New Zealand Alexandra Louise Wilson 2013 i ii Abstract North Island brown kiwi (NIBK, Apteryx mantelli), an endemic New Zealand species, are estimated to have declined by 90% from pre-human colonisation numbers. Currently, at least 60% of mortality is attributed to introduced mammalian predators, namely stoats (Mustela erminea) preying on chicks. Therefore, conservation effort focuses on predator trapping/killing, and hatching and rearing NIBK chicks in captivity and releasing them back into the wild. These efforts are resulting in increased recruitment of chicks into populations. However, little is known about the biology and behaviour of NIBK chicks in the wild and how this may affect management of these populations. Consequently, the aim of this study was to examine the ecology of young wild NIBK in a natural high density population with reduced predator diversity on Ponui Island. More specifically, the goal was to determine their growth rates, behaviour around the natal nest, dispersal and mortality, and how these factors may be influenced by environmental variables. During the 2010 - 2011 and 2011 - 2012 breeding seasons 29 young NIBK were observed from hatching until mortality or the end of 2012. -

TAS Trinidad and Tobago Birding Tour June 14-24, 2012 Brian Rapoza, Tour Leader
TAS Trinidad and Tobago Birding Tour June 14-24, 2012 Brian Rapoza, Tour Leader This past June 14-24, a group of nine birders and photographers (TAS President Joe Barros, along with Kathy Burkhart, Ann Wiley, Barbara and Ted Center, Nancy and Bruce Moreland and Lori and Tony Pasko) joined me for Tropical Audubon’s birding tour to Trinidad and Tobago. We were also joined by Mark Lopez, a turtle-monitoring colleague of Ann’s, for the first four days of the tour. The islands, which I first visited in 2008, are located between Venezuela and Grenada, at the southern end of the Lesser Antilles, and are home to a distinctly South American avifauna, with over 470 species recorded. The avifauna is sometimes referred to as a Whitman’s sampler of tropical birding, in that most neotropical bird families are represented on the islands by at least one species, but never by an overwhelming number, making for an ideal introduction for birders with limited experience in the tropics. The bird list includes two endemics, the critically endangered Trinidad Piping Guan and the beautiful yet considerably more common Trinidad Motmot; we would see both during our tour. Upon our arrival in Port of Spain, Trinidad and Tobago’s capital, we were met by the father and son team of Roodal and Dave Ramlal, our drivers and bird guides during our stay in Trinidad. Ruddy Ground-Dove, Gray- breasted Martin, White-winged Swallow and Carib Grackle were among the first birds encountered around the airport. We were immediately driven to Asa Wright Nature Centre, in the Arima Valley of Trinidad’s Northern Range, our base of operations for the first seven nights of our tour. -

Attempting to See One Member of Each of the World's Bird Families Has
Attempting to see one member of each of the world’s bird families has become an increasingly popular pursuit among birders. Given that we share that aim, the two of us got together and designed what we believe is the most efficient strategy to pursue this goal. Editor’s note: Generally, the scientific names for families (e.g., Vireonidae) are capital- ized, while the English names for families (e.g., vireos) are not. In this article, however, the English names of families are capitalized for ease of recognition. The ampersand (&) is used only within the name of a family (e.g., Guans, Chachalacas, & Curassows). 8 Birder’s Guide to Listing & Taxonomy | October 2016 Sam Keith Woods Ecuador Quito, [email protected] Barnes Hualien, Taiwan [email protected] here are 234 extant bird families recognized by the eBird/ Clements checklist (2015, version 2015), which is the offi- T cial taxonomy for world lists submitted to ABA’s Listing Cen- tral. The other major taxonomic authority, the IOC World Bird List (version 5.1, 2015), lists 238 families (for differences, see Appendix 1 in the expanded online edition). While these totals may appear daunting, increasing numbers of birders are managing to see them all. In reality, save for the considerable time and money required, finding a single member of each family is mostly straightforward. In general, where family totals or family names are mentioned below, we use the eBird/Clements taxonomy unless otherwise stated. Family Feuds: How do world regions compare? In descending order, the number of bird families supported by con- tinental region are: Asia (125 Clements/124 IOC), Africa (122 Clem- ents/126 IOC), Australasia (110 Clements/112 IOC), North America (103 Clements/IOC), South America (93 Clements/94 IOC), Europe (73 Clements/74 IOC ), and Antarctica (7 Clements/IOC).
