Located on the northwest coast of Ross Island in McMurdo Sound, Cape Bird features virtually unweathered surface drift with erratics from the Transantarctic Mountains (TAM) and with enclosed marine shell fragments. This Cape Bird drift is cut by Holocene beaches. The chronology of drift deposition and beach formation comes from AMS radiocarbon dates of associated marine shells, and of penguin b...

This paper focuses on the synthesis of bird songs using Hidden Markov Models (HMM). This technique has been widely used for speech modeling and synthesis. However, features and contextual factors typically used for human speech are not appropriate for modeling bird songs. Moreover, while for speech we can easily control the content of the recordings, this is not the case for bird songs, where w...

Bird populations are known to be affected by climate and habitat change. Here we assess on a continental scale the relationship of a bird population index for the Pied Flycatcher (Ficedula hypoleuca) with spatially explicit long-term climate data. For 1971-2001 and using multiple linear regression and AIC selection methods for candidate models we found that log-transformed 30 year long-term fal...

Bird damage is a common and costly problem for fruit producers, who try to limit damage by using management techniques. This analysis used survey data from producers in five U.S. states to estimate bird damage to sweet cherry (Prunus avium) crops with and without the use of bird management. A partial equilibrium model was applied to the data to estimate the change in the marginal cost of produc...
