They occur naturally from the up the hardness of wood, fundamental leaf anatomy, and other lands in the tropics to the limits of tree growth near the Arctic characteristics. The soft or white pines usually have needles in Circle and are widely grown throughout the world for timber clusters of five with one vascular bundle visible in cross sec and as ornamentals.

Reproductive Success and Nest-Site Selection in a Cooperative Breeder: Effect of Experience and a Direct Benefit of Helping

Nest predationwas high; only 17%of breed- ing attemptsresulted in fledgedyoung. The heightof nestswas an importantdeterminant of success;low nestswere significantlymore successfulthan high nests.A breeder'sage, natal nestsite, and breedingexperience had no significanteffect on nest-siteselection. How- ever,failed breeders who helped at thesuccessful nests of conspecificsbuilt subsequentnests lowerthan nestsbuilt prior to their helpingexperience. Failed breeders who did not help showedno reductionin tlseheight of subsequentnests. Moreover, the subsequentrepro- ductivesuccess of failed breederswho helped was significantlyhigher than that of failed breederswho did not help.We concludethat helpersgain informationon nest-sitequality throughtheir helping experience and thus gain a directfitness benefit from their cooperative behavior.We suggest that experience as a helperoffers a morereliable cue to nest-sitequality thanbreeding experience because helpers are associatedwith nestsonly during the nestling phasewhen few nestsare depredated.In contrast,although successful breeders may expe- riencesuccess with a low nest,they are evenmore likely to haveexperienced the failureof low nestsbecause of the high rate of nestpredation.

It was here that most of the group met up, had lunch and used the facilities, with all of us being rather impressed by the choice of music in the lavatories: bird song! A few members of the group commented on the fact that there was no snow outside, which was the expected sight. It was soon time for us to board our next flight to Oulu, a journey of only one hour, but during the flight the snow levels quickly built up on the ground below us. We landed around 5pm and met a few more of our group at baggage reclaim. Once everyone had collected their luggage, we exited into the Arrivals Hall where our local guide Ari was waiting to greet us. Ari and Alice then collected our vehicles and once everyone was on board, we headed to Oulu’s Finlandia Airport Hotel, our base for the next two nights, which was literally ‘just down the road’ from Oulu Airport. -
