And Anna's Hummingbirds
Rufous (Selasphorus rufus) and Anna’s Hummingbirds (Calypte anna) population changes in Western Washington by Lauren N. Rowe A Senior Project Submitted in Partial Fulfillment of the Requirements for the Degree of Bachelor of Science (Wildlife Conservation) School of Environmental and Forest Sciences University of Washington Box 352100 Seattle, Washington 98195-2100 2018 Rufous (Selasphorus rufus) and Anna’s Hummingbirds (Calypte anna) population changes in Western Washington Lauren N. Rowe Abstract Western Washington is home to a large variety of bird species including Rufous Hummingbirds (Selasphorus rufus) and Anna’s Hummingbirds (Calypte anna). Hummingbirds’ diets largely consist of nectar from blooming flowers or from human provided hummingbird feeders. Rufous Hummingbirds are long-distance migrants and travel to Washington to breed and their arrival date in Washington State has been earlier due to climate changes (Courter 2017). In Washington, Rufous Hummingbirds are in decline (Sauer, et al., 2017). Anna’s Hummingbirds have undergone a large range expansion and now are present in Washington year round. One large reason Anna’s Hummingbirds have been able to expand northward is by the use of exotic flowering plants in gardens and hummingbird feeders providing an additional food source (Birds of North America, 2017). This study will utilize data acquired from a survey sent out to Audubon Society members in western Washington about their hummingbird feeders, what species they see, and if there has been a change in Rufous or Anna’s Hummingbirds sightings over the years to try to answer questions related to the population changes of both of these species in the past several years. -

Red high status and either high biological vulnerability or high action need Category Range Score Status -20 to 20 10 Biological -50 to 50 -24 Action -40 to 40 16 Higher numerical scores denote greater concern Status - variables measure the trend in a taxon’s population status or distribution. Higher status scores denote taxa with known declining trends. Status scores range from -20 (increasing) to 20 (decreasing). Score Population Trend in Alaska (-10 to 10) 10 Declining throughout their range in Canada and the U.S. (Sauer et al. 2013; Warnock 2017a). In Alaska, data from the Breeding Bird Survey (BBS) found a non-significant trend for both short-term (2003-2015) and long-term (1993-2015) analyses (Handel and Sauer 2017). However, sample sizes are small and the BBS may not be appropriate for monitoring this species because of its affinity for artificial feeders (Cotter and Andres 2000a). Short-term data from off-road surveys suggest a declining trend in Alaska (Handel and Sauer 2017). Distribution Trend in Alaska (-10 to 10) 0 Unknown. Status Total: 10 Biological - variables measure aspects of a taxon’s distribution, abundance and life history. Higher biological scores suggest greater vulnerability to extirpation.

Neotropical Birding 24 2 Neotropical Species ‘Uplisted’ to a Higher Category of Threat in the 2018 IUCN Red List Update
>> FEATURE RED LIST 2018 The 2018 IUCN Red List in the Neotropics James Lowen, Hannah Wheatley, Claudia Hermes, Ian Burfield and David Wege Neotropical Birding 21 featured a summary of the key implications for the Neotropics of the 2016 IUCN Red List for birds. This article briefs readers on the main changes from the 2018 update. s part of its role as the IUCN Red List BirdLife’s Red List team updated the Authority for birds, BirdLife International information available for roughly 2,300 species A is responsible for assessing the global worldwide. Globally, this resulted in changes to conservation status of each of the world’s 11,000 the categorisation of 89 species; 58 species were or so bird species, allocating each to a category ‘uplisted’ to a higher category of threat, whilst ranging from Least Concern to Extinct. The latest roughly half that number – 31 species – were update was published in November 2018 (BirdLife ‘downlisted’. In the Neotropics, 13 species were International 2018). Although much more modest uplisted (Fig. 2) and slightly more – 18 – were in reach than the comprehensive update carried downlisted (Fig. 5). Now let’s take a closer look at out in 2016, whose Neotropical dimension was the individual changes, largely using information discussed in Symes et al. (2017), the 2018 revamp made available on BirdLife’s ‘Globally Threatened contains a suite of interesting changes for species Bird Forums’ (8 globally-threatened-bird- occurring in the Neotropical Bird Club region that forums.birdlife.org). Is the picture quite as rosy as are worth drawing to readers’ collective attention. -

Life History Account for Allen's Hummingbird
California Wildlife Habitat Relationships System California Department of Fish and Wildlife California Interagency Wildlife Task Group ALLEN'S HUMMINGBIRD Selasphorus sasin Family: TROCHILIDAE Order: APODIFORMES Class: AVES B292 Written by: M. Green Reviewed by: L. Mewaldt Edited by: R. Duke, S. Granholm DISTRIBUTION, ABUNDANCE, AND SEASONALITY A common summer resident (January to July) and migrant along most of the California coast. Breeders are most common in coastal scrub, valley foothill hardwood, and valley foothill riparian habitats, but also are common in closed-cone pine-cypress, urban, and redwood habitats. Occurs in a variety of woodland and scrub habitats as a migrant. Although mostly coastal in migration, fairly common in southern mountains in summer and fall migration (Garrett and Dunn 1981), and a few occur regularly in the Sierra Nevada (Gaines 1977b). Very rare in fall, and rare to uncommon in spring, on the Farallon Islands (DeSante and Ainley 1980). The subspecies S. s. sedentarius is a common resident of the Channel Islands (except San Nicolas and Santa Barbara islands, where it is an occasional visitant), and of the Palos Verdes Peninsula, Los Angeles Co. (Garrett and Dunn 1981). SPECIFIC HABITAT REQUIREMENTS Feeding: Hovers to take nectar from a wide variety of herbaceous and woody flowering plants; also eats insects and spiders. Cover: Cover is provided by shrubs and trees near foraging areas. Reproduction: Often attaches nest to more than one lateral support on eucalyptus, juniper, willow, other trees, vines, shrubs, or ferns. Nest sometimes placed at end of branches of shrub or tree or on tree trunk; often placed in shade of overhanging cover. -
Life History Account for Rufous Hummingbird
California Wildlife Habitat Relationships System California Department of Fish and Wildlife California Interagency Wildlife Task Group RUFOUS HUMMINGBIRD Selasphorus rufus Family: TROCHILIDAE Order: APODIFORMES Class: AVES B291 Written by: M. Green Reviewed by: L. Mewaldt Edited by: R. Duke, S. Granholm DISTRIBUTION, ABUNDANCE, AND SEASONALITY A common migrant and uncommon summer resident of California. A rare, but probably regular, winter resident in southern California (Garrett and Dunn 1981). A common breeder in Oregon and Washington, and breeding in the Trinity Mts. of Trinity and Humboldt cos. has been confirmed in recent years (McCaskie et al. 1979, 1988). Many postbreeders migrate south through the Cascade Range and Sierra Nevada in summer, although spring migration mostly is through the lowlands and foothills (Grinnell and Miller 1944). Found in a wide variety of habitats that provide nectar-producing flowers; uses valley foothill hardwood, valley foothill hardwood-conifer, riparian, and various chaparral habitats in both northward and southward migration; montane riparian, aspen, and high mountain meadows (to tree-line and above) used in southward migration. More common in the southern deserts in southward than in northward migration. On the Channel Islands, a rare spring migrant (Garrett and Dunn 1981). On the Farallon Islands, very rare in spring and uncommon in fall (DeSante and Ainley 1980). SPECIFIC HABITAT REQUIREMENTS Feeding: Takes nectar from many species of flowering plants; also eats insects, spiders and tree sap. Hovers while taking nectar and insects, which it gleans from foliage and flowers; also hawks insects from air. Cover: Trees and shrubs in many habitats provide cover, including lowland riparian, open woodlands, scrub, and chaparral, also mountain meadows extending to and above treeline (Grinnell and Miller 1944).
