Weekly Roundup – Ending April 5, 2015

This past week brought several migrant findings including:  Black-throated Gray Warbler, Ash-throated Flycatcher, Western Tanager, and multiple sightings for the Black-headed Grosbeak and Wilson’s Warbler.

Oddly enough, the Tanager, Grosbeak and Warbler were all males.  Females of these species were nowhere to be found as Ryan points out below they typically arrive here first to locate territory

I’ve included several images below – comments welcome – thanks for visiting.

Summer Tanager (note: this is a vagrant, not a migrant – thanks again Ryan)

Male Summer Tanager taken at Serrano Creek Trail on April 5, 2015.  Bird located by a pedestrian who pointed out the finding to Mike Sanders and I.  In order to locate this species you had to squat below a large branch of the Mulberry tree and view up.

    In many cases the males migrate first so they can begin staking their claims to territories, with females arriving a little bit later. However, I did have male and female Black-headed Grosbeaks arrive at my house at the same time a week or two ago, whenever they showed up here this year.

    Also, Summer Tanager would be a vagrant in OC. Western is the only actual migrant we get here. So a male or a female, whichever, is rare. Having two together at the same spot would be even rarer, so it is not unusual that you didn’t have any female tanagers there accompanying that male.
