The field of nature names is constantly expanding to include all species of flowers and trees and animals and birds and even fish. In addition to its appeal for anglers, Pike recalls Zebulon Pike, the explorer who discovered and gave his name to Pike's Peak.

Worthy sibling for Oak, Elm, Juniper, and Spruce.

Mostly feminine, though "Office" star Rainn Wilson gives it a slight masculine twist. You might also use this as a short form of Raines.

River shares the tranquil feeling of all the water names, and seems to have pretty much escaped its past strong association with River Phoenix and his unfortunate fate. Actor Joaquin Phoenix named his son with actress Rooney Mara after his brother River.

Now that it's no longer fashionable for girls, Robin is rising for boys again. Robin Hood, Robin Williams, Christopher Robin, and Robin the Boy Wonder are all male namesakes, after all. It reentered the US Top 1000 boys names in 2015 for the first time since 1999 and continues to bounce around the lower end of the Top 1000.

How many decades will it take for Rocky to triumph over its association with Sylvester Stallone's battered but not beaten boxer? The moment may have come, now that Sarah Michelle Gellar and Freddie Prinze Jr. have named their son Rocky. It helps, too, that Madonna's son Rocco helped make the name child-appropriate again.

Though as a formal name Rusty is a little, well, rusty, it spent half a century among the Top 1000, departing only in 1995. Only 45 baby boys received the name in the US in one recent year and it's difficult to imagine it as the winning choice of many modern parents. Whether you want an informal name or a spin on a traditional name or even a word name or a name that means red, there are simply too many better options.

Shell has been used as a short form of Shelley for all genders and Sheldon for boys. That was then: Now, Shell can be a beachy nature name and word name turned baby name.

A handsome, spruced-up post-Bruce tree name.

Thatcher is an open and friendly freckle-faced surname, fresher sounding than Tyler or Taylor, that dates back to the days of thatched-roof cottages. It is catching on with modern parents—it reached the US Top 1000 for the first time in 2013.

Other wild animals like Fox, Wolf and Bear are catching on as baby names, and Tiger is a rarer option with several famous namesakes, including golf champ Tiger Woods, who was born Eldrick. Other famous Tigers include Indian actor Tiger Shroff, born Jai, and British actor Tyger Drew-Honey, who spells his name with a Y.

Wolf is a name with a split personality. It can be seen as one of the fierce animal names, like Fox and Bear and Puma, with a touch of the werewolf, or it can be viewed as a quieter, Wolf Blitzer kind of name, fairly common in German (where is pronounced Vulf) and Jewish families, sometimes as a short form of Wolfgang, or even Wolfram or Wolfhart.

Wren may not be as time-honored a bird name choice as Robin or even Lark, but it's more fashionable and fresh, with a gentle and earthy vibe.
