More head patterns

Congratulations - you have completed More head patterns. You scored %%SCORE%% out of %%TOTAL%%. Your performance has been rated as %%RATING%%
Your answers are highlighted below.
Question 1
The two white stripes are the:
supercilium and lateral throat stripe
auriculars and malar
supercilium and malar
Question 2
And the species is:
Black-chinned Sparrow
Dark-eyed Junco
Five-striped Sparrow
Black-throated Sparrow
Question 3
The black stripe on the head is on the:
malar
crown
auriculars
supercilium
Question 3 Explanation:
Unlike most birds, which have a dark stripe on the side of the crown contrasting with a paler eyebrow stripe, this species has the black stripe shifted lower on the side of the head. The crown is completely blue-gray, and the supercilium is partly black. Actually I think you could say the black spreads up a little bit onto the edge of the crown, so I'll give partial credit for "crown".
Question 4
The species is:
Lucy's Warbler
Black-tailed Gnatcatcher
Northern Mockingbird
Blue-gray Gnatcatcher
Question 5
Is the throat paler or darker than the supercilium? Is the throat paler or darker than the supercilium?
about the same
darker
paler
Question 6
The species is:
Curve-billed Thrasher
Northern Mockingbird
California Thrasher
Canyon Towhee
Question 7
The white stripe below the eye is on the:
throat
auriculars
malar
supercilium
Question 7 Explanation:
All woodpeckers that have a black-and-white pattern below the eye have the colors reversed from the norm (compare the position of the dark and light stripes with the Black-throated Sparrow above). On most birds the auriculars are dark, often with a darker lower border (called a moustachial stripe since it originates near the nostrils). If there is a paler stripe below the auriculars it is on the malar (submoustachial), and there is often another dark stripe below that on the side of the throat. Woodpeckers, however, have a pale moustachial stripe originating near the nostrils and extending back along the lower edge of the auriculars. The malar (submoustachial) feathers along the side of the lower jaw are dark, and the throat is entirely pale.
Question 8
The species is:
Downy Woodpecker
Nuttall's Woodpecker
Three-toed Woodpecker
Hairy Woodpecker
