1 STF = small tree finch, WPF = woodpecker finch
2NTU = non-tool-user, TU = tool-user, NA = not applicable (small tree finch)
3humid=wet (Scalesia) Zone at high altitude; arid=dry zone at lower altitude
4Experiments involving the manipulation of a tool-like implement are underlined. Trap tube experiments from this study are denoted with superscript (*).
1 = box opening task(general learning task testing perseverance in solving a novel operant task, Teschke et al. unpublished); 2 = reversal task(general learning task testing flexibility, Teschke et al. unpublished);3=seesaw task(physical task testing sensitivity to surface continuity, Teschke et al. unpublished); 4=cane task(physical task testing sensitivity to the functional relationship between a reward and the tool used to attain it, Teschke et al. unpublished); 5=two-trap tube (Experiment 1, this study); 6=modified two-trap tube (Experiment 2, this study); 7= modified two-trap tube without pre-inserted piston(Experiment 3, this study); 8=contact task (task which again involved pulling a pre-inserted stick, but required the birds to attend to the necessity of contact between a tool-like impliment and the reward,unpublished data). Order of numbers representing experiment participation are in order of actual presentation.
