Pine (Pinus, family Pinaceae) reproduction takes two years. At the beginning of year one (shown here), ovulate cones are pollinated, but the female gametophtyes in the cones are not yet mature. The pollen remains in the cone until the beginning of year two, when fertilization occurs, and seeds begin to develop. This specimen of a cultivated European species was photographed May 18, 2007 in Marion County, Ohio, USA.

Apparently, it is characteristic of the Scots Pines (Pinus sylvestris) of the Abernethy Forest that they tend to grow tall and straight, and they were of such good quality that they were used in the building of ships, amongst other things. The tall, straight specimens pictured here are exposed to the prevailing westerlies across Loch Mallachie. Moray, Scotland.

Pine Warbler (bright male)

 

From the "More Than Your Really Wanted To Know Department"...

 

Until recently [i.e., until publication in 2011 of the "52nd Supplement to the American Ornithologists' Union Check-list of North American Birds" in The Auk 128(3):600-613], the Pine Warbler's Latin name was Dendroica pinus. Based largely on recent analyses of mitochondrial and nuclear DNA, the genus Dendroica, as we knew it, is no more. As noted on page 608 of the referenced publication:

 

"Under the heading Genus SETOPHAGA Swainson, insert the following:

Notes.—Phylogenetic analyses of sequences of mitochondrial and nuclear DNA (Lovette et al. 2010) indicate that all species formerly placed in Dendroica, one species formerly placed in Wilsonia (citrina), and two species formerly placed in Parula (americana and pitiayumi) form a clade with the single species traditionally placed in Setophaga (ruticilla). The generic name Setophaga has priority for this clade."

 

So, it seems our familiar Pine Warbler (formerly Dendroica pinus) is now officially treated as Setophaga pinus. Of course, I'm assuming everyone on the receiving end of this is as keenly interested in the recent taxonomic turn as am I. Yeah, right! Whatever, it's still a Pine Warbler.
