Reducing pesticide use at homes, gardens, and greenspaces is an important way to help these species. Pet owners should be aware that many topical flea and tick medications are neonicotinoid-based and can enter the environment when animals go outside or are washed. Choosing food grown without pesticides also makes a difference. This extends to birdseed, much of which is grown with intensive pesticide use.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Habitat loss, including loss of nesting sites, is another driver. Modern buildings are often designed without eaves, with bird exclusion purposely in mind. This can reduce local nesting opportunities for species like Barn Swallows. If aerial insectivores are nesting on your building, consider yourself lucky and do what you can to protect them.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<h4><\/h4>\n<h4>One species is bucking the trend<\/h4>\n<p><span data-contrast=\"auto\">The one bright spot is the <a href=\"https:\/\/birdweb.org\/Birdweb\/bird\/western_flycatcher\">Western Flycatcher<\/a>, counts of which have grown exponentially along nearly every forested NBP survey loop in recent years, with overall counts up 572%. Why this species booms while close relatives like Western Wood-pewee or Olive-sided Flycatcher bust isn\u2019t entirely clear. Western Flycatchers make a shorter migration and favor shaded interior forests, so fewer threats along the way, maturing forest at NBP sites, or both may help explain their success.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=&#8221;1_2,1_2&#8243; _builder_version=&#8221;4.27.0&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;1_2&#8243; _builder_version=&#8221;4.27.0&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_image src=&#8221;<a href=\"https:\/\/birdsconnectsea.org\/wp-content\/uploads\/2026\/02\/wefl_trajectory_earthcare.png&#038;#8221\">https:\/\/birdsconnectsea.org\/wp-content\/uploads\/2026\/02\/wefl_trajectory_earthcare.png&#038;#8221<\/a>; title_text=&#8221;wefl_trajectory_earthcare&#8221; _builder_version=&#8221;4.27.0&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_image][\/et_pb_column][et_pb_column type=&#8221;1_2&#8243; _builder_version=&#8221;4.27.0&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text _builder_version=&#8221;4.27.0&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<p>WEFL = Western Flycatcher<\/p>\n<p>The only aerial insectivore species analyzed that had upward population trends.<br \/><em><\/em><\/p>\n<p><em>Photo by Jason C Scoggins, Audubon Photo Awards<\/em><\/p>\n<p>[\/et_pb_text][et_pb_image src=&#8221;<a href=\"https:\/\/birdsconnectsea.org\/wp-content\/uploads\/2026\/02\/Aud_APA-2022_Western-Flycatcher_A1_17610-4_Photo-Jason-C-Scoggins-Web-size.jpeg&#038;#8221\">https:\/\/birdsconnectsea.org\/wp-content\/uploads\/2026\/02\/Aud_APA-2022_Western-Flycatcher_A1_17610-4_Photo-Jason-C-Scoggins-Web-size.jpeg&#038;#8221<\/a>; title_text=&#8221;Aud_APA-2022_Western-Flycatcher_A1_17610-4_Photo-Jason-C-Scoggins-Web size&#8221; align=&#8221;center&#8221; _builder_version=&#8221;4.27.0&#8243; _module_preset=&#8221;default&#8221; module_alignment=&#8221;center&#8221; max_height=&#8221;249px&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=&#8221;4.27.0&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.27.0&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text _builder_version=&#8221;4.27.0&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; custom_margin=&#8221;17px|||||&#8221;]<\/p>\n<h4>Why this matters<span data-ccp-props=\"{}\"><\/span><\/h4>\n<p>Local, long-term community science like the Neighborhood Bird Project turns observations into insight.
