<div>Thoughts as I stand in line at the airport…</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">—migration behavior is very much part of a species niche</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">—resident birds have an advantage over migrants because they don’t endure the hazards of migration</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">—nesting sites may be the limiting factor causing birds to migrate; food not so much in the breeding season when food can be abundant</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">—birds are especially suited to migrate because their physiology favors them</div>

<div style="line-break:after-white-space">Greetings. I have been thinking about the relationship between urban birds and mountains birds. When I am up in the mountains, I often see some of the birds of my Seattle yard, such as juncos, robins, and black-capped
chickadees. It’s my understanding that “my” yard birds do not migrate up to the mountains. Is this correct?
<div><br>
</div>
<div>In contrast, I believe that the varied thrushes I see in my yard do migrate up to the Cascades. Is this correct?</div>
<div><br>
</div>
<div>Any insights on the connection between birds seen in the Cascades ones in the urban/Puget lowland landscape would be appreciated.</div>
<div><br>
</div>
<div>Sincerely,</div>
<div>David </div>
