Clark’s Nutcracker’s relies on Whitebark Pine as a primary food source for feeding young in early spring with seeds that had been cached the previous autumn 1. The large seeds produced by many of these species are and important food source for the Clarks nutcracker and similar birds and grizzly and black bear.

The relationship between the whitebark pine (Pinus albicaulis), an iconic tree of western mountaintops, and the Clark's Nutcracker (Nucifraga columbiana), a Fewer five-needle white pines leads to fewer cones, which leads to fewer Clark’s nutcrackers. Whitebark pine is in decline throughout its range, due to infection by white pine blister rust (Cronartium ribicola), widespread outbreaks of mountain pine beetle, and … Whitebark pine mutualism. Many birds will inadvertently plant some shrubs and other vegetation after seeds pass through their digestive track. There is a close association between Clark's Nutcracker and Whitebark Pine, a conifer that usually occurs in high, dry mountainous areas. Clark’s Nutcracker and Whitebark Pine have a tight relationship, each depending upon the other, in the Rocky Mountains. Whitebark pine is a preferred food for the nutcracker which, in turn, is responsible for most whitebark pine dispersal and regeneration. Then, an amazing process unfolds: the nutcracker tucks the seeds, sometimes more than a 100, into a special pouch beneath their tongues. Previous research has revealed that in whitebark pine (Pinus albicaulis) habitat, the frequency of Clark’s nutcracker occurrence decreased with lower whitebark pine cone production [7,8]. Clark’s Nutcracker Whitebark Pine Seed Dispersal Effectiveness. 1. Bold. Clark’s Nutcrackers by caching pine seeds in the ground have contributed to seed dispersal for the whitebark pine and forest regeneration (Tomback). A single Clark’s nutcracker can hide up to 100,000 seeds a year. Whitebark pine seedlings are generally considered hardy after their 1st few weeks of life [17,208].Seedlings rapidly grow deep roots and thick, drought-resistant stems [], enabling whitebark pine seedlings to better survive drought compared to their more sun-intolerant conifer associates.Even so, droughty, coarse-textured soils may reduce whitebark pine establishment. Without nutcrackers, whitebark pines might never have made it to these mountains. But it’s long, prominent bill, … A bit of research revealed this ‘pine crow’ to be a Clark’s Nutcracker. Observed proportion of observation hours with Clarks nutcracker occurrence 2360 versus proportion of hours predicted from cone production index using (A) McKinney et 2361 al.s [11] and (B) Barringer et al.s [12] models. By John Fraley. Most cones grow horizontally on the tips of the vertical branches that make up most of the crown ensuring that the cones are highly visible and accessible to birds. “Whitebark pine has no other means for regeneration,” Schaming said. Between September and December it stores seeds to eat later, placing 30–150 seeds in the pouch under its tongue and carrying them to a spot nearby or up to 15 miles away.” Download this stock image: Clark's Nutcracker (Nucifraga columbiana) eating seeds from its favourite food plant, the Whitebark Pine (Pinus albicaulis), Western USA - W7NJM7 from Alamy's library of millions of high resolution stock photos, illustrations and vectors. The relationship between the whitebark pine (Pinus albicaulis), an iconic tree of western mountaintops, and the Clark’s Nutcracker (Nucifraga columbiana), a brash bird in the crow family, is often used as an example of the biological concept of mutualism: a relationship between species where both benefit.The pine provides large, nutritious seeds to the nutcracker. 2. Big. 1. The diagonal line represents a perfect 2362 - "Clark's nutcrackers and whitebark pine: Resilience of a keystone mutualism in an altered ecosystem" However, the seeds not retrieved will germinate, thus contributing to forest regeneration.

Clark's Nutcracker is in the crow and jay family, but the first time Captain William Clark saw one, in August of 1805, he thought it was a woodpecker. Nutcrackers have a mutualistic relationship with whitebark pine, being the primary agent of dispersal for the pines, which in turn are a major source of food for the nutcrackers throughout the year (Lanner 1996, Tomback 1998).

Most, it will dig up during the snowy months ahead. It shells seeds by cracking them in its bill or by holding them in its feet and hammering them.
