12. Bird Brains? Transitive inference Episodic memory Object constancy (follow disappeared object) Tool manufacture Social learning Theory of mind (Nihei and Higuchi 2001)

13. All Bird Brains are Not Equal (Emery and Clayton 2004)

14. Hippocampus In birds and mammals most medial part of pallium Spatial memory (caches, location of danger) Changes in size with seasonal needs

15. Lateralization and Brain Complexity Complex neural connections and lateralization –Left hemisphere for complex integration and learning New Caledonian Crows are mostly right-billed (tilting to use right eye), using left hemisphere to guide tool making and use Song learning is also controlled from left hemisphere (Cnotka et al. 2008)

17. Fig. 1. FROM DELANEY et al. 2008---Distribution of Island and Western scrub-jays, with associated geographic trends in morphological characteristics. Species distributions are adapted from Curry et al. (2002); orange = Aphelocoma insularis, green = Californica group of Aphelocoma californica, light blue = Woodhouseii group of Aphelocoma californica, and dark blue = sumichrasti group of Aphelocoma californica. Florida Scrub-jay Scrub-jays Currently we recognize 3 species, but there are most likely 5 and maybe 6 isolation has been of paramount importance and novel selective pressures from foods eaten (oaks versus other seeds)

18. During the last several million years land connections (via Beringia) between New and Old Worlds waxed and waned with glaciation. Beringia was dry and offered land passage. 50ka

19. Corvids Invade Our World Tied to changes in vegetation and sea level Tertiary forests of Australia were being replaced by deserts perhaps forcing corvid ancestors (related to Birds of Paradise and Orioles) to leave Australia and head north in Oligocene and Miocene to Asia, following northward movement of tropical forests 6-8 mya in Miocene New World Jay ancestor from forests of southeast Asia, radiate in South America (first) and North America 15,000 ya – 2 mya in Pleistocene Old World Jay (Gray Jay) Nutcracker Magpie Crow Raven (from article on evolution of cats; Johnson et al. 2006; Science 311:73-77)

20. Ravens 4 clades diverging in Africa 1.7- 3.8my Corvus corax ancestor diverges (closest relative is C. albus) shortly thereafter C. corax invades New World 2my and new and old world ravens begin independent evolution –Old world raven spins off Canary Island Raven 650,000 yr –New world ravens spins off Chihuahuan Raven C. corax reinvades New World 15,000 years ago

21. Complexity Revealed By Genetic Analyses Common Raven –~15,000 years ago old world ravens again invaded the new world via Beringia Holarctic and California clade of ravens now found in North America, but they are becoming more similar, not diverging as they had in past. –Giving us new insights into what constitutes a “species”
