FROM THE PREZ I would like to take this
opportunity to thank every-one for supporting the Pa-louse Audubon Society. We have had a very productive year—sponsoring many field trips and successful monthly program meetings. Our present financial cof-fers are such as to now al-low us to offer grants in support of students working
toward our chapter's goals of conserving and restoring our natural ecosystems, focusing on birds, other wildlife, and their habitats for the benefit of humanity and the earth’s biological diversity.
I wish everyone a won-derful and happy holiday season and hope that you will find time to join us on
one or both of the annual Christmas Bird Counts this December and January. The Palouse Audubon Soci-ety wishes everyone a Merry Christmas and Happy New Year,
Terry Gray President

Cedar waxwings are one of three waxwing species in the family Bombycillidae. A unique character of the family is the “wax” on the tips of secondary wing feathers (see pic-ture). When originally described, the tips were thought to be similar to “drops of sealing wax” that were exuded or secreted from the feather. A careful examination shows that they are actually flattened ex-tensions of the feather shaft (quill) and are made of the same ma-terial as the shaft. Feathers grow out-ward from a follicle in the skin, (similar to a hair or fingernail), thus, the unique “wax” tip would be the first feature to form on a wax-wing secondary. Although the tips appear to be a glob of wax from above, they ap-pear as flattened scales
from the side. The vibrant red color is from a common c a r o t e n o i d p i g m e n t (astaxanthin) derived from
fruit in the waxwings’ diet and the pigment is depos-ited in the feather as the tip forms.
The function of the red tips is speculative. It has been suggested that they protected or preserved the tips of secondary feathers
although it was not clear why secondary tips would need such protection. Quantitative studies have
documented that birds less than a year old had fewer and smaller tips than older birds. Males tended to-ward more and longer tips than females but differ-ence was not sig-nificant. The tips might be another example of plum-age elaboration or o r n a m e n t a t i o n that is common in birds and is thought by most
researchers to provide vis-ual cues of status. In the waxwing, the number and size of the tips could pro-vide reliable signals of an individual's age, but not sex.

Audubon Washington staff are often asked what the State office is working on in regards to Global Warming. Right now, we are focusing on a national campaign, the C-Change Global Warming Campaign. The purpose of this campaign is two-fold: to generate pressure on targeted swing congressional members and to create climate change champions among our senators to ensure stronger conservation legislation from the next Administration.
There are three primary components to this cam-paign. The first is pre-election tasks. We have been seeking opportunities to discuss climate change at public forums, local candidate debates, and other public meetings. On October 15th, the “Feeling the Heat Report” was also released. Audubon Washing-ton collaborated on this report focusing on rising global temperatures and what implications tempera-ture trends might have for our state.
Another component of the campaign is ongoing tasks. Our office has been sending letters to three target audiences: grassroots leaders within our state, state university presidents, and local businesses. Through these letters, we are urging participation in this campaign to encourage Congress to reduce car-

The third component of this campaign will occur post-election. We are working to coordinate meetings between legislative members, local business leaders, university fac-ulty, and other interest groups. The C-Change group will also focus on a “100 Days Campaign” urging swift federal action for the environment in the first 100 days of the new administration.
This is what the State office is working on, but we still need some help from chapters. We can’t make an impact unless you do. Audubon’s unique strengths are its chapters and volunteers. Here are some examples of how you can get involved: Write an editorial to your local paper

play their tips to potential mates in “side hopping” display. In this display, a bird hops along a perch toward, then away, from another bird. Typically, a fruit is presented to a potential mate who recip-rocates the display or swallows the fruit. The secondary tips would be clearly evi-dent as a bird displays, however as yet, there are no experiments that prove the tips serve a signaling function. One study with waxwings has shown that older waxwings have higher reproduc-tive success which might provide the adaptive rationale for the evolution of such a status signal.
Another interesting aspect of waxwing coloration is a link to an increase in the incidence of orange tail bands to the spread of invasive Morrow honeysuckle. Typically, cedar waxwings have a bright yellow band on the tips of their tail. However, in the last 35 years birds with orange tail bands have appeared in east-ern North America. Experiments have shown that orange pigment is derived from non-native Morrow honeysuckle berries eaten by waxwings. Orange tails were found initially in juveniles because of the coincidence of honeysuckle berry ripening and the growth of juveniles’ tails. The adult molt cycle, when the tail is entirely replaced, occurred after ber-ries were available. As the honeysuckle has become more wide spread, it appears that berries now are available to molting adults in some part of the waxwings’ range during the normal molt cycle re-sulting in orange tails in both age groups. Orange-tailed cedar waxwings have not been reported in Washington yet, but when they appear it will likely be confused with the Japanese waxwing which typically has an orange tail band.

If Black-capped Chickadees consulted with real estate agents about their housing needs, they'd be easy to please with regard to neighborhoods, accept-ing a variety of habitats from pristine forests to suburban backyards and urban parks. But chickadees are fussy about house design and prefer to excavate their own cavities. They'd be drawn to a listing for a “fixer-upper for the do-it-yourself homeowner”. Scientists have learned a great deal about social interactions, bird personalities, brain neuron regeneration, how ultraviolet plumage color influences mate choice, and other issues by studying Black-capped Chickadees, but there are gaps in our understanding of their basic nesting habits. Chickadee nest cavities have such tiny entrance holes that it's difficult for re-searchers to get the inside story except by studying them in nest boxes.
Chickadees prefer birdhouses filled with wood shavings, giving them something to excavate. Standard nest boxes have long been available in Sap-sucker Woods but were rarely used by chickadees. Even boxes filled with shavings aren't as readily accepted as researchers, and bird watchers, would like. So we (Caren and David) set out to learn whether chickadees would more readily accept an “artificial tree snag” made from a PVC tube. We based our design on a model devel-oped by Thomas Grubb and C.L. Bronson in Ohio in the 1990s.
Starting in 2005, we gave chickadees a choice of nest-ing options near the Lab of Ornithology in Sapsucker Woods. With a team of helpers, we grouped one artificial snag and one standard nest box at 20 sites in Sapsucker Woods. At each site, the nest box and the snag were filled with wood shavings. We located eight of the sites next to existing unfilled nest boxes. Entrance holes for the structures at each site were oriented in the same direction.
Each year of the study, chickadees excavated 60-70 percent of the artificial snags, but only 40-50 percent of the filled nest boxes. They built nests in 25-30 percent of the snags but in only 15 percent of the filled nest boxes, and seldom nested in empty boxes. Their selec-tion of artificial snags may have been influenced by the higher entrance holes in the snags and/or because the snags were less accessible to mice, but the preference was clear.
House Wrens and mice compete with chickadees for nest sites. Neither wrens nor mice excavate their own

cavities, but they often take over one after chickadees have excavated it. We found that artificial snags were no more
likely than boxes to attract wrens, and none were taken by mice, sug-gesting that the snags may be less susceptible to other climbing predators as well. Not everyone wants a camouflage-painted PVC pipe rather than a standard birdhouse in their back-yard. But if you're trying to inter-est a pair of chickadees in relocat-ing near you, these artificial snags may be an excellent choice. Plans a r e a v a i l a b l e a t www.birdscope.org.
