This adult female Red Crossbill caused a few smiles last week as it was a first for the banding station. The age of the bird was determined by its wrinkled brood patch. This is a patch of featherless skin that is visible on the underside of birds during the nesting season.

MacGillivray's Warbler

Geothlypis tolmiei 

Appearance:
Stocky, sluggish warbler
Olive upperparts
Yellow underparts
White crescent above and below eye
Full gray hood, covering head, nape and throat
Male:
     Dark, charcoal gray hood
     Black area in front of eyes
Female:
     Paler gray hood
Immature: (photographed)
     Whitish-gray chin and throat

Listen to its call.

I haven't read anywhere that MacGillivray's Warblers have particularly short tails but this little one sure did. In fact, it was almost non-existent as can be seen in the picture below.  Anyone have any insight on this?

UPDATE:  Since my original post, I have discovered that this hatch year bird was probably going through its preformative molt. Typically during this molt, not all of the feathers are replaced.  However, I read that juveniles sometimes lose their entire tail prematurely and when it regrows it features adult rectrices.

Wilson's Warbler

Cardellina pusilla

Appearance:
Small songbird
Yellow underparts and face
Olive green back
Dark wings and tail
Male:
     Black cap

 Listen to its call. 

Day two of banding turned up a number of new birds for me, including this hatch year, male Wilson's Warbler.  What a handsome bird! It's not surprising they call a group of warblers a 'bouquet'.

House Wren

Troglodytes aedon 

Appearance:
Small, compact bird
Fairly long, curved bill
Longish tail
Gray-brown upperparts
Dull, grayish-white underparts, including sides of head
Dark barring on wings and tail
Juvenile:
     Blackish mottling on breast

Listen to its call.

This is another hatch year bird that we banded last weekend.

Most wrens are small and brown with short wings and tails which they often hold upright. So, how do you tell them apart? Well, here are a few distinguishing features that help with wren identification.

• House Wren -- curved bill, faint eyebrow, fairly long tail and dingy breast
• Bewick's Wren -- straight bills, bold eyebrow and white breast
• Pacific Wren -- almost no tail, bold eyebrow, smaller and darker than House Wren

Pacific-slope Flycatcher

Empidonax difficilis

Appearance: 
Small flycatcher 
Pale yellow to white, teardropped shaped eye-ring
Two white wingbars 
Greenish-brown back 
Yellowish underparts 
Yellow lower mandible
Immature:
     Wingbars buffy in colour

Listen to its song.

This weekend, I had the pleasure of volunteering at RPBO's banding site for the first time.  I thoroughly enjoyed the experience with one exception.  The 5 am start time was for the birds!

Not only is the experience helping with my bird identification, I'm also learning a lot about aging the birds.  This little flycatcher was one of the many birds that stopped in for a visit. Its buffy wingbars identify it as a juvenile.

Pacific Golden-Plover

Pluvialis fulva

Medium-sized plover
Moderately long legs
Large head
Large, dark eyes
Golden and black speckled back

    Black speckling along the white border by the underparts and under tail
Non-breeding plumage:
    Buff wash with dark speckling on the breast
Juvenile:

    Yellowish head and breast

Listen to its call. 

When I initially spotted this shorebird, I thought it was a Black-bellied Plover as they are fairly common around Victoria. It wasn't until I was reviewing my photos later that I realized my mistake. There are a number of differences between the two species, one of which I found a bit ironic. There is more black on the belly of the Pacific Golden-Plover then on the Black-bellied variety.

I was photographing peeps on the beach last week when this bird suddenly swooped in looking for dinner, resulting in mass exodus. Fortunately, both for me and the tiny sandpipers, he went away hungry -- but not before I was able to get some nice photos.
