Juneau Birds in Winter -- A Slide Show
Tree Swallow Season Summary 2020 By Jessica Millsaps · Of the 58 Tree Swallow nest boxes JAS put up around Juneau this year, 49 boxes had swallow eggs laid in them, 9 were unused, and 3 were taken over by Chestnut-backed Chickadees.
· Tree swallows laid a confirmed total of 283 eggs with average clutch size being 6 eggs.
· The largest clutch had 8 eggs (an unusually high number for this species).
· Of 283 eggs, only 14 failed to hatch.
· The first chick hatched 6/7 and the last one hatched 7/4.
· A total of 254 chicks hatched with 191 chicks successfully ledged.
· 2 nests were predated and 7 nests failed, possibly due to cooler than average temperatures.
· The first chicks to fledge took flight 6/24 and the last ones to fledge finally left 7/28 (probably our latest record). 41 nests successfully fledged some chicks but only 16 nests were 100% successful with no losses.
Coffee and Birds Many Alaskan birds, such as Tennessee Warbler and Swainson’s Thrush, winter in the mountains of Latin America. They are looking for trees, bushes, insects and fresh water to survive. Sometimes, they find themselves in a coffee farm. Learn More HERE. Juneau Removes Protections for Bald Eagle Nests -- January 2018 By Gwen Baluss In January, 2018, the CBJ Assembly narrowly voted to re-move extra protections for Bald Eagles that limited development and disturbance within 350 of active nests and 50 feet of non-active nests. The reason given was that there was no way to enforce the rule and no federal biologists available to find and check on eagle nests. This rule change no doubt will be a disappointment to those who want to see the local eagle population continue to thrive, and are concerned that nests will be disturbed. However, eagles are still protected by the Migratory Bird Treaty Act and the Bald and Golden Eagle Protection Act, which prohibits anyone, without a permit issued by the Secretary of the Interior, from "taking" bald eagles, including their parts, nests, or eggs. The CBJ also drafted Best Management Practices, where developers can voluntarily be better neighbors to eagles. Some eagles can be quite tolerant to development. Now, it may be in part up to citizens to keep tabs on known nests, to ensure that eagles are not being hassled. If you know of an eagle’s nest that does not already have a yellow eagle sign at the tree base, it’s a good idea to document its exact location (such as a GPS point, or a pinpoint on Google Maps), and the dates that birds are using it, especially when the young are present. If there is a development planned nearby, or you are concerned that an eagle or any raptor has been jeopardized, inform the US Fish and Wildlife Service 907-780-1160 . State
Watchlist Birds in Southeast Alaska Part IV: A Refuge for Hummingbirds?
By Gwen Baluss We continue to discuss the Audubon "Red" watchlist for Alaska, updated in 2017. The list uses the best avail-able trend information to highlight species that are in decline, or especially vulnerable to big population drops, and for which key parts of the birds’ habitat is within Alaska. What species is on the cover? The Rufous Hummingbird. We are lucky to encounter this species frequently during Southeast Alaska’s short summers. Their arrival is celebrated in April; they are even the center of birding, arts and other fun events at the Ketchikan Hummingbird Festival. Usually the first sightings are males, but both males and females set up shop between mid-April and early May. The males don’t help at all with the nest or nest-lings and take off by July 1. Females begin to migrate out in July and are rarely seen after August 1. A few young birds may linger in to fall, but they too are mostly gone by the first week in August. Rufous hummingbirds breed throughout the Pacific Northwest and Northern Rocky Mountains. They winter in Mexico, especially in the Sierra Madre mountains. Some also use drier parts of Mexico or the US Gulf states. Hummingbirds eat a variety of insects and spiders in addition to nectar and sap from sapsucker wells. Unfortunately, multiple broad scale bird surveys suggest a potential decline in the species. Because hummingbirds behave differently than most songbirds, being more clustered around food sources such as flowers, the differences detected could be related to different flowering patterns and not differences in hummingbird populations. However, different flowering times could mean trouble for these migratory birds as the climate warms. Other concerns that have come to light recently include: changes in flower availability due to climate change or land use change, drying of forests in the northern Rocky Mountains, fire suppression in the Sierra Madre, systemic pesticide use, and wide use of hummingbird feeders. Perhaps Alaska will be become more important as a breeding area, remaining lush and moist as parts of the Northwestern US be-come drier. What can we do? Support initiatives that help pollinators. These will help hummingbirds too. Support limits to use of systemic pesticides (neonicotinoids) both at home and in Mexico. Plant organically grown flowers. This is the safest way to enjoy hummingbirds. Wondering what the best plants are? The new USDA guide Maintaining and Improving Habitat for Hummingbirds in Alaska compiles information about hummingbird habitat and food habits: goo.gl/MmXBck If you decide to keep a feeder, keep in mind that it’s a commitment to keep the birds safe. Think about any hazards including windows. Avoid feeders with sharp edges or small downward facing holes (birds can get startled and catch a bill or feet in these). Clean and scrub all surfaces of feeders at least twice a week. Mold can kill hummingbirds. Boil white sugar and water only, no dye or brown- colored sugar. State Watchlist Birds in Southeast Alaska: Part II, A Super Migrant in Decline - Lesser YellowlegsIn December, Dr. Nils Warnock, Executive Director for Audubon Alaska, spoke in Juneau about the latest Audubon watchlist for Alaska. The list uses the best available trend information to highlight species that are in decline, or especially vulnerable to big population drops – and for which key parts of the birds’ habitat is within Alaska. Last month, I discussed three red-listed species from this list that may be found in winter locally: Greater Scaup, Yellow-billed Loon and Marbled Murrelet. I continue the discussion this month with a bird that
passes through Southeast AK on its journeys: Lesser
Yellowlegs. This species breeds in bog areas throughout
much of interior AK and boreal Canada. They like to forage
in open, shal-low mud areas such as river mouths and
wetlands.
Lesser Yellowlegs are complete migrants, meaning there is no overlap between breeding and non-breeding range. And they cover a lot of distance. Boreal breeding birds may be heading into South America. Its not known how and if the birds divide up by sub-population into different continental routes or flyways. A fascinating presentation about this, along with interesting results from tagged birds can be found here . The results show that birds from Anchorage went essentially all over the Americas. For example, one bird stopped over in New Brunswick and Guyana before spending most the winter in Argentina. I always assumed that a Lesser Yellow-legs I saw at Mendenhall wetlands in August was using the Pacific flyway and heading for places like the estuaries of Northern California and Isthmus of Tehuantepec, Mexico, because these are places I happened to have seen groups of them. If there is a Pacific coast movement that parallels movement seen along the Atlantic and through the middle of the continent, it does not seem to be published yet for individual birds. A surprising threat has been identified for yellow-legs: hunting at migratory stopovers. With the exception of snipe and limited subsistence take, hunting of shorebirds is rare in North America, thanks to their inclusion in the Migratory Bird Treaty, and something most birders think of as only a past, not a current conservation threat. However, these birds do not enjoy the same protection though out their entire range. For example, in Barbados, a key strategic stopover point for exhausted birds traveling towards South America in the fall, hunting is a long-term tradition. Luckily, entities like the US FWS and Birdlife International are working with the hunters in Barbados on species conservation and voluntary limits. However, the story could be different in places such as Guyana where apparently all shore-bird species can be hunted. What can we do? Support healthy wetlands and estuaries, where these birds stop to feed. The Mendenhall Wetlands Important Bird Area often has concentrations yellowlegs. It is threatened by continued adjacent urban development, and sewage treatment. If you see a bunch of these birds report it in eBird. Hotspots in migration could be important information. Around Juneau, dogs chasing shorebirds could have an impact. Yellowlegs have a long, long, ways to go—disrupting important feed-ing time could affect their schedule, making them more vulnerable to problems they may face on the way, such as storms. Encourage those you know to keep the pups close when around shorebird feeding hotspots. Support organizations and government groups that study shorebirds such as: US Fish and Wildlife Service in Alaska, University of Alaska at Anchorage, Alaska Department of Fish and Game, and Birdlife International. Report Lesser Yellowlegs in eBird, especially if wandering out in our many "underbirded" areas of remote Southeast Alaska. Beginning birders will enjoy this challenge: separating from Greater Yellowlegs. Be sure to look closely at the bill length, com-pared to the rest of the head. State Watchlist Birds in Southeast Alaska: Part I, Winter By Gwen Baluss Recently Dr. Nils Warnock, Executive Director for Audubon Alaska, spoke in Juneau about the latest Audubon watchlist for Alaska. The list uses the best available trend information to highlight species that are in decline, or especially vulnerable to big population drops, and for which key parts of the birds’ habitat is within Alaska.
This will be the first article of a series discussing the red-listed watchlist species that are found locally in Southeast Alaska, and some ideas about what we can do to help these birds.
The following birds may be found on the Christmas Bird Count (CBC) for Juneau. Information gained on the CBC is part of the picture that scientists use to make assumptions about species declines and changes of ranges. We thank all volunteers who help with this event. Greater Scaup These ducks often
congregate in our area during spring and fall migration,
occasionall
Reasons for widespread and serious declines over past decades are not known. There are many hypotheses; contamination issues and loss of boreal wetlands as permafrost melts are strong contenders.
What can we do? If you hunt or know hunters, consider passing on taking scaup. Since it’s difficult for most to quickly distinguish the greater from the lesser scaup, and there are also some concerns about both species; avoiding both is a safe option. Suggest targeting more common species, such as mallards. Currently the limit in Southeast game unites is 7 ducks per day (freshwater types, with no more breakdown by species given). This could give the false impression that all duck populations are equally abundant in Alaska. Nationwide, waterfowl species in general are well managed by a collective of federal and regional coordinators, and hunters have been a positive force in habitat conservation. As a result, many duck populations are doing well. However, local regulations have not caught up with national conservation pri-orities. Report large flocks of scaup on eBird. A good summary of how to tell the two species apart can be found online here . Greater Scaup are often seen in salt water. Add this "freshwater" duck to the countless species that will benefit from any initiative keeping our water clean. Yellow-billed Loon Audubon Alaska
lists a global population for this species at only about 24,
000. Southeast Alaska is lucky to have a smatter-ing of observations near most communities, and is considered part of its normal winter range. This species is not considered endangered by the US Fish and Wildlife Service (USFWS), but concern has led to extensive assessment of its threats and information needs.
According to the Alaska Department of Fish and Game, "Breeding habitat loss or degradation, reduction of prey base due to overfishing, incidental mortality in fisheries, subsistence harvest, and predation are the main potential threats to yellow-billed loons."
The good news for this species is that it is on the radar of managers in Alaska. Acording to the USFWS "The Conservation Agreement (Agreement) for the yellow-billed loon (YBLO) Gavia adamsii," has been developed as a cooperative effort among local, state and federal re-source agencies in northern and western Alaska in order to take measures necessary for the conservation of the species."
What can we do? Speak up for the federal and state agencies who employ trained biologists to responsibly monitor and inform the public about wildlife manage-ment. Budget cuts and vilification from the public continue damper the effectiveness of agencies to do their job.
Contribute to knowledge of where these birds breed and range by reporting observations in eBird. In winter it can be quite difficult to distinguish at a distance from the Common Loon. In fact, a quick perusal of biding forums on the internet will yield vigorous discussion and plenty of conjecture by hopeful watchers. An advanced birding guidebook is helpful to distinguish the two.
Support fisherman who are taking measures to reduce or eliminate by-catch of seabirds. Marbled Murrelet Southeast Alaska
is a hotspot for this species, where we can enjoy by lower
research
The watchlist states "Threats in Alaska include marine regime shifts that affect food supply, predation by avian predators, incidental bycatch in gillnet fisheries, and logging of old growth habitat."
What can we do? Support fisherman who are taking measures to pro-tect seabirds. Support conservation and research for recover of the small bait fish eaten by murrelets. Consider that Marbled Murrelets in Southern-most Alaska could be affected by timber sales of large trees. (Note that murrelets do use other habitats, such as mossy rocks, farther north). Maintaining water quality in the Inside Passage will help murrelets.

Tips for Safe Bird-feeding
Hummingbird feeders should be changed twice a week. All surfaces should be scrubbed with a brush (you can buy small bottlebrushes online or try using pipe cleaners for the small holes). Soak first in vinegar if any mold has formed. Glass reservoirs can also be sanitized with very hot water. Avoid feeders with plastic storage reservoirs, and any surface that are not easy to clean. Feeders with holes that are on a flat platform should be drilled to make at least as big as a standard school pencil eraser; smaller holes on a flat plane can catch birds beaks or legs and cause serious injury if something startles them.
JAS Supporting Bird Research and Monitoring by Gwen Baluss As an organization JAS has historically been focused on environmental education and conservation in Southeast Alaska, with a focus on birds and wildlife. This is still true, but we also recognize the importance of monitoring and research, especially of bird population for both our migratory and resident species. Here are a few ways we help. Christmas Bird Count – this is a long-standing, wide range count that Audubon supports. The data from the CBC is now being used to see how birds’ winter range, distribution and populations have changed over time. Comparing this with climate data we can see how some birds have shifted northwards in the winter.Other citizen science efforts - we are always encouraging our members to use eBird so their data can be pooled with this great emerging database. Specifically, we try to publicize special count events such as the Great Backyard Bird Count, and the Global Big day. Even our field trips are usually entered in to eBird and make for several fairly consistent springtime “snap shots” of the bird life, with plenty of skilled observers.
Arctic Tern Monitoring – New this year, JAS in partnership with US Forest Service plans to sponsor an Intern who will study and help protect Arctic Terns around Mendenhall Lake.

View Facebook video: https://www.facebook.com/jos.bakker.543/videos/1708694369142029/ Moose in Juneau: sometimes it’s not so crazy to hope By Gwen Baluss I’ve hung my rain cap here in Juneau for most the time since 1998. Something I always pondered is, where are the moose? It didn’t seem fair that Gustavus and Petersburg would have them, and Juneau didn’t. They were up the Taku and Berners Rivers, but wouldn’t venture in between? I made it a point to bring up my inquiry in conversations with biologists, naturalists, and hunters. Sometimes the answer was "lack of habitat". I never bought this one, as I looked around at plenty of the plants that the browsers enjoy in other parts of Southeast: willow, highbush cranberry, even blueberry. A more persuasive answer was simply "dispersal rate." According to ADF&G reports, moose only started appearing in Southeast Alaska in general in the early twentieth century. The moose simply hadn’t found this habitat that, on geologic terms, is new and still being uncovered as glaciers recede. And the fact that other communities were colonized first had to do with proximity to a direct river from interior Alaska-- and some luck. There had been a few sightings over the years around Juneau though. I even saw the pellets of a cow that had been reported at, of all places, Moose Lake. I eagerly awaited the day when more moose would show up near the Juneau Road system. Starting in fall 2013, I noticed tracks and browse around Point Bridget State Park, apparently of a cow and at least one calf. A Juneau Empire story reported sightings "out the road" as well that fall. The following year, I found more tracks and sign. But despite many hours devoted to sneaking around in the rain, never saw even a glimpse. Finally, in fall 2015, I had the incredible luck to see a cow, a grown bull and small bull, all together near Cowee Creek. And the excitement builds as recently there has been solid evidence of a cow and bull in Mendenhall Valley; also, a cow in the Thunder Mountain bowl and a young bull at Boy Scout Beach. Where did these moose come from? Perhaps some DNA work will tell us in the years to come. It seems most likely that the animals traveled from Berners Bay. That population there was introduced in 1958 and 1960 with 17 and 11 animals respectively, stock from the Mat-su Valleys. But of course, wildlife dispersal is not always as one would assume. Moose dispersed into Southeast Alaska from British Columbia. The Anderson subspecies (Alces alces andersoni) colonized different areas in a complex pattern, sometimes established by only a few "founders", but with potential for mixing with subsequent incursions of the larger interior Alaska moose subspecies (Alces alces gigas), especially in the Haines and Yakutat areas. (An interesting write up about this can be found here: http://www.adfg.alaska.gov/index.cfm?adfg=wildlifenews.view_article&articles_id=602). What’s going to happen next? A handful of animals is hardly a population yet, but at least we have the right elements to spur the imagination. Juneau will be different if moose become frequent denizens. I wonder about the human and wildlife interactions. Will drivers learn to slow down going out the road in the evenings? Will animals be shot by poachers? How many loose dogs will be stomped if there is a mom and calf roaming the Mendenhall Glacier Recreation area? Nobody is more eager to see the moose than I, but cringe the community might love the animals to death: naming them, feeding them, approaching too close to get photos. ("Romeo" the wolf comes to mind here). Either way, it’s bound to make our fall walks around Juneau more exciting for a while.
