a. chimpanzee stacking up boxes to reach a banana
b. ravens pulling up a string to obtain attached food item
c. injury-feigning behavior of ground-nesting bird
d. the cognitive map of jay that enables it to retrieve food from its many catches
e. all of the above show evidence of information processing and animal cognition
i was leaning towards E as well because the first 3 options clearly demonstrate cognitive behavior

i have a pair of zebra finch.male is so cutet and so active.he always sing and jump from here to there.he keep making nest,so far he has made 3 nest in 3 differnet boxes.once he completed one nest he start to make another and left previois one.but FEMALE does not take any interest in nest, neiter see the nest.as both are 9months old and this will be their first breeding,male built nest but they have not mate yet.what is wrong with my female .plz tell me this is my first time breeding finch or any birds.

From the author: Although it is commonly believed that nest boxes yield artificially high estimates of nest success, few investigators have compared nesting success in nest boxes to tree cavities in the same locality during the same time period. I studied nesting success of Great Crested Flycatchers (Myiarchus crinitus) breeding in nest boxes and natural sites (i.e., old woodpecker cavities and natural tree hollows) on the same pine plantations in northern Florida. Mayfleld estimates of nesting success were nearly identical between nest boxes (0.37 [+ or -] 0.05 SE, n 32 nests) and tree cavities (0.38 [+ or -] 0.06 SE, n 27 nests) during a 2-year period. However, nesting success was greater in nest boxes (0.53 [+ or -] 0.06 SE) than in cavities (0.33 [+ or -] 0.10 SE) during 1997 and lower in nest boxes (0.26 [+ or -] 0.07 SE) than in cavities (0.42 [+ or -] 0.09 SE) during 1998. Lower nest success in nest boxes during 1998 was due to increased predation during the incubation period. Nest predation accounted for 83% of all ne st failures. Documented nest predators included the southern flying squirrel (Glaucomys volans) and corn snake (Elaphe guttata). Nest boxes and cavity nests did not differ significantly in any habitat variable that would influence nest concealment, nor did these variables differ significantly between years. Evidence suggests that nest predators may learn to exploit nest boxes as a prey resource, either through the development of search images or through long term spatial memory. This study demonstrates that nest boxes are not always safer sites than tree cavities and that static comparisons may give misleading results.

Phoenix is exploring the cockatiel cage and the nest box. Saphron the daddy cockatiel is tolerant but not real pleased about it.
Its a bird that I see alot of in CT I don’t know what its called anyway, my horses were kicking the shelter boxes and a nest fell out the parents took both of the other siblings and never came back for this one. I put it in a bucket with some grass and paper towels I read along time ago to soak dry cat food and feed them it. He wont eat the food how should I give it water and how often what should you put in their environment? help!
