    • Effects of landmark distance and stability on accuracy of reward relocation 

      Pritchard, David James; Hurly, T. Andrew; Healy, Susan Denise (2015-07) - Journal article
      Although small-scale navigation is well studied in a wide range of species, much of what is known about landmark use by vertebrates is based on laboratory experiments. To investigate how vertebrates in the wild use landmarks, ...
    • The foraging behaviour of hummingbirds through space and time 

      Tello Ramos, Maria Cristina (University of St Andrews, 2015-07-27) - Thesis
      Central place foragers, such as territorial hummingbirds, feed from resources that tend to be constant in space and to replenish with time (e.g. nectar in flowers). The ability to remember both where and when resources are ...
    • Treating hummingbirds as feathered bees : a case of ethological cross-pollination 

      Pritchard, D. J.; Tello Ramos, M. C.; Muth, F.; Healy, S. D. (2017-12) - Journal item
      Hummingbirds feed from hundreds of flowers every day. The properties of these flowers provide these birds with a wealth of information about colour, space and time to guide how they forage. To understand how hummingbirds ...
    • Wild hummingbirds can use the geometry of a flower array 

      Hornsby, Mark A. W.; Healy, Susan D.; Hurly, T. Andrew (2017-06) - Journal article
      Animals use cues from their environment to orient in space and to navigate their surroundings. Geometry is a cue whose informational content may originate from the metric properties of a given environment, and its use has ...
    • Wild rufous hummingbirds use local landmarks to return to rewarded locations 

      Pritchard, David James; Scott, Renee D.; Healy, Susan Denise; Hurly, Andrew T. (2016-01) - Journal article
      Animals may remember an important location with reference to one or more visual landmarks. In the laboratory, birds and mammals often preferentially use landmarks near a goal (“local landmarks”) to return to that location ...
