However, in southern California where the Anna\u2019s hummingbird has long occurred, our observations indicate that this species may be experiencing a local decline.&nbsp; We hypothesize that the highly aggressive nature of a relatively new arrival to the southern California mainland, i.e. the Allen\u2019s hummingbird (Selasphorus sasin), is pushing out and restricting the Anna\u2019s hummingbird to marginal habitat. We investigate temporal variation in the proportion of territories occupied by Anna\u2019s vs. Allen\u2019s hummingbirds on and around campus. Before the pandemic, we collected data on spatial variation (and likely ecological segregation) of these hummingbird species. Our goal is to determine whether patterns from several years ago have changed over time. Formerly, we hypothesized that Anna\u2019s will likely be replaced by Allen\u2019s hummingbird territories in the natural areas surrounding campus, as the Allen\u2019s expand outside their foothold in the campus garden areas. We currently test this hypothesis, with the null being no change in relative abundance of Allen\u2019s vs. Allen\u2019s since pre-pandemic levels. This research has implications for the conservation of a potentially vulnerable bird population that is being adversely affected by changes in the biotic community.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading\">Presentation<\/h2>\n\n\n<iframe loading=\"lazy\"  id=\"_ytid_43531\"  width=\"720\" height=\"405\"  data-origwidth=\"720\" data-origheight=\"405\"  data-relstop=\"1\" src=\"https:\/\/www.youtube.com\/embed\/zqWAWWQFrrA?enablejsapi=1&#038;autoplay=0&#038;cc_load_policy=0&#038;cc_lang_pref=&#038;iv_load_policy=1&#038;loop=0&#038;rel=0&#038;fs=1&#038;playsinline=0&#038;autohide=2&#038;theme=dark&#038;color=red&#038;controls=1&#038;disablekb=0&#038;\" class=\"__youtube_prefs__  no-lazyload\" title=\"YouTube player\"  allow=\"fullscreen; accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen data-no-lazy=\"1\" data-skipgform_ajax_framebjll=\"\"><\/iframe>\n\n\n<div class=\"wp-block-file\"><a id=\"wp-block-file--media-de627b2c-9036-4f26-91b9-bdb3df1d1d20\" href=\"https:\/\/src.cikeys.com\/2022\/wp-content\/uploads\/2022\/05\/Henry-Avelar-Holding-Down-the-Fort.pdf\">Presentation File<\/a><a href=\"https:\/\/src.cikeys.com\/2022\/wp-content\/uploads\/2022\/05\/Henry-Avelar-Holding-Down-the-Fort.pdf\" class=\"wp-block-file__button\" download aria-describedby=\"wp-block-file--media-de627b2c-9036-4f26-91b9-bdb3df1d1d20\">Download<\/a><\/div>\n<\/div>\n<\/div>\n\n\n\n<iframe src=\"http:\/\/docs.google.com\/gview?url=https:\/\/src.cikeys.com\/2022\/wp-content\/uploads\/2022\/05\/Henry-Avelar-Holding-Down-the-Fort.pdf&#038;embedded=true\" style=\"width:100%; height:600px;\" frameborder=\"0\"><\/iframe>\n","protected":false},"excerpt":{"rendered":"<p>Henry Avelar, Shane Stoyko, Lauren Powell, Jamie Abanes, Katya Contreras, Alexis Samuel, Ernest Wallace, and Dr. Allison Alvarado<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"categories":[4],"tags":[9],"class_list":["post-61","page","type-page","status-publish","hentry","category-poster","tag-biology","post"],"_links":{"self":[{"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/pages\/61","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/comments?post=61"}],"version-history":[{"count":6,"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/pages\/61\/revisions"}],"predecessor-version":[{"id":707,"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/pages\/61\/revisions\/707"}],"wp:attachment":[{"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/media?parent=61"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/categories?post=61"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/tags?post=61"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
