The account identifies the important qualities of a species through a scientific drawing. This then leads to exploration of the interrelationship of the Clark’s Nutcracker (a type of woodpecker) and the whitebark pine.

In our study, we used the term “home range” to describe the BACKGROUND area used by a resident nutcracker for all year-round activities We investigated habitat use, caching behavior, and except seed harvest.

Field Guides Tour Report Taiwan 2020 Feb 1, 2020 to Feb 12, 2020 Phil Gregory & local guide Arco Huang For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. This gorgeous male Swinhoe's Pheasant was one of the birds of the trip! We found a pair of these lovely endemic pheasants at Dasyueshan. Photo by guide Phil Gregory. This was a first run for the newly reactivated Taiwan tour (which we last ran in 2006), with a new local organizer who proved very good and enthusiastic, and knew the best local sites to visit. The weather was remarkably kind to us and we had no significant daytime rain, somewhat to my surprise, whilst temperatures were pretty reasonable even in the mountains- though it was cold at night at Dasyueshan where the unheated hotel was a bit of a shock, but in a great birding spot, so overall it was bearable. Fog on the heights of Hohuanshan was a shame but at least the mid and lower levels stayed clear. Otherwise the lowland sites were all good despite it being very windy at Hengchun in the far south. Arco and I decided to use a varied assortment of local eating places with primarily local menus, and much to my amazement I found myself enjoying noodle dishes. The food was a highlight in fact, as it was varied, often delicious and best of all served quickly whilst being both hot and fresh. A nice adjunct to the trip, and avoided losing lots of time with elaborate meals. -
Thailand Highlights 14Th to 26Th November 2019 (13 Days)
Thailand Highlights 14th to 26th November 2019 (13 days) Trip Report Siamese Fireback by Forrest Rowland Trip report compiled by Tour Leader: Forrest Rowland Trip Report – RBL Thailand - Highlights 2019 2 Tour Summary Thailand has been known as a top tourist destination for quite some time. Foreigners and Ex-pats flock there for the beautiful scenery, great infrastructure, and delicious cuisine among other cultural aspects. For birders, it has recently caught up to big names like Borneo and Malaysia, in terms of respect for the avian delights it holds for visitors. Our twelve-day Highlights Tour to Thailand set out to sample a bit of the best of every major habitat type in the country, with a slight focus on the lush montane forests that hold most of the country’s specialty bird species. The tour began in Bangkok, a bustling metropolis of winding narrow roads, flyovers, towering apartment buildings, and seemingly endless people. Despite the density and throng of humanity, many of the participants on the tour were able to enjoy a Crested Goshawk flight by Forrest Rowland lovely day’s visit to the Grand Palace and historic center of Bangkok, including a fun boat ride passing by several temples. A few early arrivals also had time to bird some of the urban park settings, even picking up a species or two we did not see on the Main Tour. For most, the tour began in earnest on November 15th, with our day tour of the salt pans, mudflats, wetlands, and mangroves of the famed Pak Thale Shore bird Project, and Laem Phak Bia mangroves. -

The Relationships of the Starlings (Sturnidae: Sturnini) and the Mockingbirds (Sturnidae: Mimini)
THE RELATIONSHIPS OF THE STARLINGS (STURNIDAE: STURNINI) AND THE MOCKINGBIRDS (STURNIDAE: MIMINI) CHARLESG. SIBLEYAND JON E. AHLQUIST Departmentof Biologyand PeabodyMuseum of Natural History,Yale University, New Haven, Connecticut 06511 USA ABSTRACT.--OldWorld starlingshave been thought to be related to crowsand their allies, to weaverbirds, or to New World troupials. New World mockingbirdsand thrashershave usually been placed near the thrushesand/or wrens. DNA-DNA hybridization data indi- cated that starlingsand mockingbirdsare more closelyrelated to each other than either is to any other living taxon. Some avian systematistsdoubted this conclusion.Therefore, a more extensiveDNA hybridizationstudy was conducted,and a successfulsearch was made for other evidence of the relationshipbetween starlingsand mockingbirds.The resultssup- port our original conclusionthat the two groupsdiverged from a commonancestor in the late Oligoceneor early Miocene, about 23-28 million yearsago, and that their relationship may be expressedin our passerineclassification, based on DNA comparisons,by placing them as sistertribes in the Family Sturnidae,Superfamily Turdoidea, Parvorder Muscicapae, Suborder Passeres.Their next nearest relatives are the members of the Turdidae, including the typical thrushes,erithacine chats,and muscicapineflycatchers.

Cooperative Breeding in Azure-Winged Magpies, Cyanopica Cyana, Living in a Region of Heavy Snowfall ’
The Condor89:835-841 0 The CooperOrnithological Society 1987 COOPERATIVE BREEDING IN AZURE-WINGED MAGPIES, CYANOPICA CYANA, LIVING IN A REGION OF HEAVY SNOWFALL ’ SHIGEMOTO KOMEDA,~ SATOSHI YAMAGISHI,~ AND MASAHIRO FUJIOKA Department of Biology, Faculty of Science,Osaka City University,Sumiyoshi-ku, Osaka 558, Japan Abstract. The frequencyof occurrenceof helpers, their age and sex, and certain behavior at nests were investigated in Azure-winged Magpies, Cyanopica cyana, living in central Japan, a region of heavy snowfall. One group of 16 birds was a summer visitor and the other two groupsof about 20 birds were resident. Out of 14 nestswe observed in 1983, six had one to two helpers, one had no helper, and at the other seven we could not confirm whether helpers attended or not. Therefore, 43% to 93% of nests had helpers. One helper was known to attend at least four nests, and seven of 14 marked individuals (50%) acted as helpers.These resultsmean that cooperativebreeding occurs regularly in this population.
