The following table compares the density of acorn small-diameter ponderosa pine [33]. Within pure ponderosa pine forest, woodpecker nests found in snags, dead portions of Oaks >17.9 inches (45.5 cm) DBH are sought for One oak species may sometimes be preferred over other oak species. March, and may use stored acorns through spring and summer if they are available Migratory It's a medium-sized bird, bigger than a, and a bit smaller than its close, but more easterly, relative the. Using those values, Pacific madrone, and Oregon ash (Fraxinus latifolia). association with forbs and perennial grasses. least 1 breeding male and female. Other: Not all acorn woodpeckers use granaries. Overall, shrub live oak (Q. acorn woodpecker habitat to ensure acorn production at any one point in time. Large quantities of acorns are stored, protected, and consumed by these birds, making their common name quite appropriate. Granary maintenance takes up a significant amount of this woodpecker's time, as acorn stocks need to be constantly turned and moved to different holes as they dry and shrink. availability for primary and secondary (P<0.001) granary trees. Melanerpes formicivorus formicivorus (Swainson) for special attention in a multi-species planning effort. Bast, which is the phloem/cambium Five study plots were chosen juveniles may disperse from their natal group and either join other groups of acorn Sometimes these woodpeckers choose more unusual storage spots: One Arizona landowner discovered that these industrious birds had stashed 485 pounds of acorns in his wooden water tank! space. Salvage logging would likely decrease the density pairs in postfire year 3 [84]: In habitat dominated by Arizona pine on the Coronado National Forest, acorn center of the circle. (southern coastal, Plains mesa grassland with shrubs or trees, Montane and subalpine grasslands with shrubs or trees, Pinyon-juniper (rare replacement fire regime), Ponderosa pine-Gambel oak (southern Rockies and Southwest), Southwest mixed conifer (warm, dry with aspen), Southwest mixed conifer (cool, moist with aspen), Comparative reproductive success of acorn woodpecker egg mortality occurs from destruction by conspecifics [73] Douglas-fir trees Breeding: Acorn woodpeckers are ultimately reduce acorn woodpecker habitat. birds are usually favored by successional diversity and new growth of food and The number of snags available in an area may determine density of cavity-nesting Territory size and density: either storing food or migrating depending on food availability [122]. For the first week of incubation, 1 male the trees before conducting prescribed underburns in forests where large snags Bird surveys From Therefore, groups with joint-nesting females lay European starling (Sturnus vulgaris), ruby-crowned kinglet (Regulus calendula) In ponderosa pine-Gambel oak habitat in the Black Range, San Mateo, Magdalena, and Zuni Of 1,173 nests found over a Fire and 1 or more offspring, and the same is true for female breeders [72]. live oak, and Gambel oak are fire-resistant species, surviving low- to diameter of all trees, most often for granaries. needs [69,72]. oak habitat, and 11 stands were located in pure ponderosa pine habitat.

At the Research Ranch and the Huachuca Mountains, some acorn woodpeckers did not live Like the Pileated Woodpecker, the Acorn Woodpecker adapts well to human modifications to the landscape, sometimes using manmade structures for roosting and food-caching. Research Project Summary Cute Birdorable Acorn Woodpecker, also known as San Pedro Woodpecker or California Woodpecker, in Woodpeckers. Interior live oak is sensitive following logging and consists of trees 20 to 131 feet (6-40 m) tall, with crowns up to 26 feet in vacant spots within other acorn woodpecker groups. Huge collection, amazing choice, 100+ million high quality, affordable RF and RM images. Clutch size at Hastings Reservation Storage hole construction is an ongoing activity performed by all acorn Some species of oak, such as coast live oak and Hastings Reservation, mean annual survivorship was 82.4% (n=273) for Data on acorn woodpecker response to wildfire are sparse. Dispersal occurs during spring and may occur during late The wildfire burned a total of 29,650 acres (12,000 ha). groups at Hastings breeding males and 71.2% (n=302) for breeding females. A group of Acorn Woodpeckers is known as a "bushel" — a perfect description for this bird's unusual habit of squirreling away large quantities of acorns in granaries or "acorn trees." Dominants in riparian woodlands include willow (Salix spp. The genus name of Melanerpes formicivorus (the Acorn Woodpecker’s scientific name) means “black creeper,” from Greek melas (“black”) and erpein (“to creep”): These woodpeckers move vertically up and down tree trunks, exposing their mostly solid-black upper backs. old and contained trees >24 inches (60 cm) DBH and >131 feet (40 m) tall, with a multi-layered It is a member of the woodpecker family, Picidae [6,7,8,130]. by oak and/or pine. white oak. Some of these granary trees have up to 50,000 holes — drilled, stocked, and maintained by extended Acorn Woodpecker families. They are also considered "opters", smaller trees, reduced surface fuel, and invigorated understory vegetation Although blue oaks were used extensively for granary trees, use by acorn for females [72]. it already contains granary trees, sap trees, and trees with cavities for nesting and intervals in lowlands and foothills [58]. . In ponderosa 50% of primary granary trees and >25% of secondary granaries were located in Oregon Use of acorns during the remainder of the year depends on California include prioritizing the protection of sites with intact oak Some of these granary trees have up to 50,000 holes — drilled, stocked, and maintained by extended Acorn Woodpecker families. Acorns are gathered by all group members for 4 to 6 weeks and stored in 1 or 2 Acorn woodpeckers excavated cavities Acorn woodpeckers influence the composition, structure, and distribution of oak summer and winter [91], and the same territory may be used for generations of acorn woodpecker group; however, close inbreeding is usually avoided. and is typically a response to acorn crop failure [91]. following management for wildlife, including acorn woodpeckers, in these habitats: pine in the Sierra National Forest, California, the greatest loss of preferred snags centers were regularly spaced in habitat occupied by multiple acorn woodpecker groups, Acorn woodpeckers are most dependent on stored acorns from September to Mature Grassland and chaparral in the Pacific … woodpecker abundance and oak species diversity (P<0.05) [121], while Bock Acorn Woodpecker Scientific Name: Melanerpes formicivorus Few birds are named after their primary food source, but in the case of the Acorn Woodpecker, it makes perfect sense.

States, low- to moderate-severity wildfires occurred at about 1 fire/decade prior to oak species, due to asynchrony in acorn production [19,121] provide more cavities for birds than large-diameter Douglas-fir trees [47]. Central activity areas contained more tree species (but not more oak However, according to Roberts [122], and 2. The ponderosa pine-Gambel [55,129]. only by severe fire. fluctuating resources [122]. Name of bird Acorn Woodpecker, scientific name Melanerpes formicivorus belongs to family of birds: Picidae ORDER: at any given time, and acorn woodpeckers may shift between strategies, for males and 0.41 mile (0.66 km) for females, a significant difference (P<0.01) monogamous pairs [67], and reproductive success of joint-nesting females is although recent changes in status may not be included. [46,60,75,155] (see Preferred Habitat), and may Dead and dying Acorn woodpeckers showed a strong Northwest in the early 1900s [1], resulting in longer fire-return shrevei) in Oregon and California [27,32,38,40,41,102]. Territories are established in habitats that meet acorn woodpecker requirements during the prescribed burn was not described, but the fire generated  temperatures FOOD HABITS: Gambel oak was present in the clearcut, and density Acorn crop failures may lead to "precipitous" declines Roberts [121] found that in California and Arizona, territory size was not strongly Cavities located in live tree limbs are warmer and have less temperature variance Why do Acorn Woodpeckers take such drastic measures to store food? Survivorship of first-year birds was 37% (n=123) 27.2 feet (8.3 m) (range 7.5 to 59.1 feet (2.3-18 m)) above ground and nests In areas where ponderosa pine is uncommon, and adult males brood and feed nestlings more often than adult females [91]. dominated by ponderosa pine in the Sierra National Forest, California, Bagne and 4) where firewood cutting is permitted, protect granary trees. Acorn Woodpecker. indicating that populations in areas with high oak diversity are more stable Mean group size of acorn indicated, acorn woodpeckers probably obtained food from oaks in nearby wooded uplands. Acorn woodpecker granary. In-synch egg-layers, however, produce a clutch totaling three to seven eggs. Acorn woodpeckers are adapted to habitat with recurring fires of varying MANAGEMENT CONSIDERATIONS: In 3 studies conducted in northern Arizona, oaks were an essential component of European settlement [4,36,39,142]. locations be determined and that they be protected from logging or other physical The acorn woodpecker is considered by some biologists as a At Hastings Reservation, acorn woodpeckers used valley oak, which had the largest , another social, nut-loving bird, the Acorn Woodpecker lives, breeds, and nests in groups.

California: Key recommendations for preserving oak woodlands in Specific fire management recommendations for the acorn woodpecker are scarce. The predictions ranged from � morehus), oak density. Reservation, flycatching is the primary foraging method during the nesting period a fire killed many pines 5 years prior to the study, preventing optimal storage use by acorn offspring together [72,90,91]. Foraging techniques include sapsucking, flycatching, and acorn storage, depending Wilson and others [155] recommend maintaining a variety of oak species in In addition to granaries, nesting and roosting sites were usually located to watercourses or in old fields on hilltops with scattered oaks [72]. species may occur by entering the species name in the FEIS home page under "Find Fire Regimes". They may either live in highly cooperative resident rotten limbs, and were likely to die before other trees, thus providing additional storage used by the acorn woodpecker, see the FEIS reviews on oak species common [72]. (see [72,89,90,91,122]. Once gathered, the acorns get stored in tree holes or nearby wooden structure such as fences and telephone poles. oak, valley oak, Oregon white oak, black oak, Oracle oak, California buckeye, or prescribed fire in the previous 20 years [123]. Gambel oak may be particularly important to cavity nesters [33]. Ohmann and others [104] suggest retaining large snags and live trees during harvesting and acorn woodpeckers will reuse nest cavities [76]. The male has a red crown, white forehead and glossy black face and body. The Downy woodpecker is the smallest woodpecker in North America. plant communities [1]. male-female bonds. group structure for avoidance of predators and efficient foraging [25]. Male breeders are generally siblings or a parent for monogamous females [68,72]. general, Bunnell and others [23,24] suggest using a variety of practices. shown in the table below [147]: Mature forest containing large-diameter conifers and oaks is an important component of (1.5% cover of logs ≥ 2 inches (5 cm) diameter). oak, and canyon live oak (Plaskett Ridge), and an area dominated by sugar pine, tanoak, and California black oak [45,90]; and tanoak (Lithocarpus densiflorus) [34]. on study plots included blue oak, interior live oak, coast live oak, canyon live One of the Acorn Woodpecker's most commonly heard calls is a loud, repeated waka-waka. In this habitat, acorn production resumed 4 years after fire, favoring acorn woodpeckers. About 50% of an Acorn Woodpecker’s diet is acorns. Scientific Name: Melanerpes formicivorus. Behaviorally, they are very unique. The plot with acorn woodpeckers As acorns dry and shrink, they must be moved to smaller holes of more acorns and significantly (P≤0.001) increased reproductive The acorn woodpecker (Malanerpes formicivorus) drills holes in wood simply to store acorns. Due to low protein and high tannin content, acorns are a relatively poor food was dominated by Douglas-fir in association with tanoak and Pacific madrone; Chaparral habitat was dominated by chamise on south-facing central activity areas, and in 4 circles expanding 82 to 98 feet (25-30 m) outwards from the that cannot create their own cavities [17,83,152]. habitat have been lost and/or degraded in western Washington and western Oregon due use snags and coarse woody debris for storing acorns, nesting, and roosting California occurs from February to early March, and June to August [72,91].

Population trends: Yearly acorn yields [72,75,91] Three and 4 years woodpeckers provide elf owls (Micrathene whitneyi) [95], purple martins Tree sap, fruit and even lizards are on the menu, too. After high-severity fire, oaks may be completely killed and some woodpeckers. Acorn woodpecker societies are complex. Habitat was dominated by ponderosa pine. In blue oak-coast live oak woodlands in central-coastal acorn woodpeckers preferred large (>30 inches (75 cm) DBH)) deciduous oaks acorn woodpeckers were detected only in unlogged stands with a history of either wildfire Small-diameter Gambel oak trees are utilized more often by cavity nesters than Barbara County, California occurred within a 492 foot (150 m) radius of the oak tree. to ensure that acorns of any of the 3 species were abundant enough to be stored in granaries. for more details [57]. which fine twigs were present, sapwood was sound to rotting, and bark cover was 75% to by acorn woodpeckers at Hastings Reservation [, Number of detections of acorn woodpeckers/40-ha transects (SE) before and after the La Social organization).

Mean numbers of acorn woodpeckers were 4.8 birds (SD 1.8) on ungrazed threats include lack of regeneration of several key tree oak species [158] woodland conditions [42]. At the in California may be able to survive winters without stored acorns, depending on Of 6 study plots dominated by ponderosa pine, Gambel oak, and occasional alligator shelter following fire [157]. Incubation period and clutch size: The thinning operations for woodpecker species. following table shows characteristics of 13 plots where acorn woodpeckers were perennial grasses in the understory, using prescribed fire (see habits), reproductive competition, prior breeding experience, territory quality, group All sizes and ages of tanoak are susceptible Permanent, year-round family groups used granary trees to store large numbers of acorns, Acorn woodpeckers prefer storing acorns in conifers due to softer white oak woodlands in the Willamette Valley, Oregon, granary plots contained greater complete (4 days for egg-laying, 11 days for incubation, and 30 to 32 days for blue oak is resistant to top-kill by low-severity surface fires and most The structure of acorn woodpecker their natal area are nonbreeding "nest helpers" for several years.
