QUIZ ANSWERS (to the ones appearing here on the right column)

....and from top to bottom as you scroll down the page:

1. Five wood-warbler species in N. Am. above Mexico walk:

- Swainson’s
- Connecticut
- Ovenbird
- N. Waterthrush
- LA Waterthrush

2. Rare wood-warbler species on the West Coast include (but are not limited to):

- Cerulean
- Swainson’s
- Connecticut
- Hooded
- Prothonotary
- Blue-Winged
- Kentucky
- Golden-Winged
- Yellow-throated
- Prairie

3. Among the approximately 114 wood-warbler species in the Parulidae family, 52 typically appear annually in N. Am. north of Mexico.

Thus, the answer is that MORE wood-warblers nest in the tropics than in N. Am. north of Mexico.

4. It’s mere opinion and speculation as to which autumn, basic plumage-appearing wood-warbler is the most challenging to identify, BUT respondents believe it’s Bay-Breasted.

That answer is plausible, given its cryptic plumage, especially on a hatch-year female that has little if any ruby-orange flanks. After hatch year males show this feature more prominently, though it can still be difficult to note.

I’d (humbly) suggest Blackpoll is easier to identify than Bay-Breasted because the former in autumn has yellow legs and wider, more prominent/resolute wingbars, among other features.

5. Yellow Warbler and American Redstart females have been documented as singers.

6. In the Upper Midwest, “weather and wind dynamics” are the most prominent factors that help determine when night-traveling migrants will arrive on the landscape during spring.

7. The Olive Warbler is the ONLY wood-warbler that nests in N. Am. north of Mexico yet is NOT a member of the Parulidae family. Instead, it is the lone member of the Peucedramidae Family.

Exercising: Stringent and laborious exercising is over blown by
many diet programs today. Weight loss success in the
long term will energise you and improve your health and wellbeing.
This type of "play" is the perfect interval workout:
high intensity moves incorporating both resistance (pulling
weight and working against gravity) and speed, followed by short periods of rest and recovery.
